Scheme 0: Synthesis of C-glycoside of formula I via removal of protective groups (Formula Removed) Any acyl protecting group R2 used is cleaved for example hydrolytically in an aqueous solvent, e.g. in water, isopropanol/water, acetic acid/water, tetrahydrofuran/water or dioxane/water, in the presence of an acid such as trifluoroacetic acid, hydrochloric acid or sulphuric acid or in the presence of an alkali metal base such as lithium hydroxide, sodium hydroxide or potassium hydroxide or aprotically, e.g. in the presence of iodotrimethylsilane, at temperatures between 0 and 120°C, preferably at temperatures between 10 and 100°C. A trifluoroacetyl group R2 is preferably cleaved by treating with an acid such as hydrochloric acid, optionally in the presence of a solvent such as acetic acid at temperatures between 50 and 120°C or by treating with sodium hydroxide solution optionally in the presence of a solvent such as tetrahydrofuran or methanol at temperatures between 0 and 50°C. Any acetal or ketal protecting group R2 used is cleaved for example hydrolytically in an aqueous solvent or aqueous mixture of solvents, e.g. in water, isopropanol/water, acetic acid/water, tetrahydrofuran/water or dioxane/water, in the presence of an acid such as trifluoroacetic acid, hydrochloric acid or sulphuric acid or aprotically, e.g. in the presence of iodotrimethylsilane, at temperatures between 0 and 120°C, preferably at temperatures between 10 and 100°C. A silyl group R2, for example trimethylsilyl, is cleaved for example in water, an aqueous solvent mixture or a lower alcohol such as methanol or ethanol in the presence of a base such as lithium hydroxide, sodium hydroxide, potassium carbonate or sodium methoxide. In aqueous or alcoholic solvents, acids such as e.g. hydrochloric acid, trifluoroacetic acid or acetic acid are also suitable. For cleaving in organic solvents, such as for example diethyl ether, tetrahydrofuran or dichloromethane, it is also suitable to use fluoride reagents, such as e.g. tetrabutylammonium fluoride. A benzyl, methoxybenzyl or benzyloxycarbonyl group R2 is advantageously cleaved hydrogenolytically, e.g. with hydrogen in the presence of a catalyst such as palladium/charcoal in a suitable solvent such as methanol, ethanol, ethyl acetate or glacial acetic acid, optionally with the addition of an acid such as hydrochloric acid at temperatures between 0 and 100°C, but preferably at ambient temperatures between 20 and 60°C, and at a hydrogen pressure of 1 to 7 bar, but preferably 3 to 5 bar. A 2,4-dimethoxybenzyl group, however, is preferably cleaved in trifluoroacetic acid in the presence of anisole.

R2 is defined as hereinbefore and represents for example hydrogen, acetyl, pivaloyl, benzoyl, tert-butoxycarbonyl, benzyloxycarbonyl, trialkylsilyl, benzyl or substituted benzyl. In case two adjacent groups R2 are linked with each other to form a bridging group they preferably form an acetal such as e.g. benzylideneacetal, a ketal such as e.g. isopropylideneketal, or an ethylene group that results in the formation of a dioxane such as e.g. the combination with 2,3-dimethoxy-butylene which is linked via position 2 and 3 of the butylene group to the oxygen atoms of the pyranose. A preferred meaning of R2 is hydrogen ortri-(C1_3-alkyl)silyl, such as trimethylsilyl or triisopropylsilyl. R' preferably denotes hydrogen or C1-4alkyl, in particular methyl or ethyl. The reduction may be conducted with a reducing agent in the presence of or without a Lewis acid. Suitable reducing agents include for example silanes such as e.g. triethylsilane, tripropylsilane, triisopropylsilane, or diphenylsilane, sodium borohydride, sodium cyanoborohydride, zinc borohydride, borane complexes, lithium aluminum hydride, diisobutylaluminum hydride, or samarium iodide.

Depending on the reducing agent the reductions may be carried out without a Lewis acid. The reaction may be carried out in a solvent such as for example methylene chloride, chloroform, acetonitrile, toluene, hexane, diethylether, tetrahydrofuran, dioxane, ethanol, water, or mixtures thereof. The solvent is preferably selected in view of the reducing agent and the optional Lewis acid. Preferred reaction temperatures are between -80 °C and 120 °C, more preferably between -30 and 80 °C. One particularly suitable combination of reagents consists for example of triethylsilane and boron trifluoride etherate, which is conveniently used in acetonitrile, dichloromethane, or mixtures thereof at temperatures from -60 °C to 60 °C. The reduction is preferably carried out in the absence of water, in particular with a content of water in the reaction mixture below 2000 ppm, even more preferably below 1000 ppm. In addition to the reducing agents mentioned above, hydrogen may be used for the reduction intended. This transformation may be accomplished in the presence of a transition metal catalyst such as e.g. palladium on charcoal, palladium oxide, platinum oxide, or Raney nickel, in solvents such as e.g. tetrahydrofuran, ethyl acetate, methanol, ethanol, water, or acetic acid at temperatures of -40 °C to 100 °C and at hydrogen pressures of 1 to 10 Torr. The glucose derivatives of formula III may be synthesized from D-gluconolactone or a derivative thereof by reacting the desired benzylbenzene compound in the form of an organometallic compound (Scheme 2a). Scheme 2a: Addition of an Organometallic Compound to Gluconolactone halogen-metal exchange (Table Removed) The Scheme 2a and the following sections describe preferred conditions and embodiments of the process according to the third aspect of this invention. The Grignard or Lithium reagent of benzylbenzene (VI) may be prepared from the corresponding brominated or iodinated benzylbenzene V either via a so-called halogen-metal exchange reaction or by inserting the metal into the carbon-halogen bond. The halogen-metal exchange to synthesize the corresponding lithium compound VI may be carried out for example with an organolithium compound such as e.g. n-, sec- or tert-butyllithium. A preferred amount of the organolithium compound is in the range from about 1 to 2 mol, more preferably about equimolar with respect to the benzylbenzene V. The analogous magnesium compound may also be generated by a halogen-metal exchange with a suitable Grignard reagent such as C3-4-alkylmagnesium chloride or bromide, for example isopropyl- or sec-butylmagnesium bromide or chloride or diisopropyl- or di-sec-butylmagnesium without or in the presence of an additional salt such as e.g. lithium chloride that may accelerate the metalation process. The specific transmetalating organomagnesium compound may also be generated in situ from suitable precursors (see e.g. Angew. Chem. 2004, 116, 3396-3399 and Angew. Chem. 2006, 118, 165-169 and references quoted therein). The Grignard reagent is preferably used in an amount in the range from about 1 to 5 mol per mol of the benzylbenzene V. The halogen-metal exchange reactions are preferably carried out between -100 °C and 40°C, particularly preferably between -80°C and 10 °C. A more preferred temperature range in the halogen-lithium exchange reaction is -80°C and -15 °C. Preferably the halogen-metal exchange reaction is carried out in an inert solvent or mixtures thereof, such as for example diethylether, dioxane, tetrahydrofuran, diethylene glycol dimethyl ether, toluene, hexane, dimethylsulfoxide, dichloromethane or mixtures thereof. Particularly preferred solvents are selected form among tetrahydrofuran, diethylene glycol dimethyl ether, hexane and mixtures thereof. The magnesium or lithium derivatized compounds thus obtained may optionally be transmetalated with metal salts such as e.g. cerium trichloride, zinc chloride or bromide, indium chloride or bromide, to form alternative organometal compounds (VI) suitable for addition. Alternatively, the organometal compound VI may also be prepared by inserting a metal into the carbon-halogen bond of the haloaromatic compound V. Lithium or magnesium are suitable elemental metals for this transformation. The insertion can be achieved in solvents such as e.g. diethylether, dioxane, tetrahydrofuran, toluene, hexane, dimethylsulfoxide and mixtures thereof at temperatures ranging from -80 to 100 °C, preferably at -70 to 40 °C. In cases in which no spontaneous reaction takes place prior activation of the metal might be necessary such as e.g. the treatment with 1,2-dibromoethane, iodine, trimethylsilylchloride, acetic acid, hydrochloric acid and/or sonication. The addition of the organometal compound VI to gluconolactone or derivatives thereof (IV) is preferably carried out at temperatures between -100 °C and 40 °C, particularly preferably at -80 to -10 °C, in an inert solvent or mixtures thereof, to obtain the compound of formula III. In case the compound VI is a lithiumorganic compound the addition is even more preferably carried out at temperatures in the range from -80 to -20°C. In case the compound VI is a magnesiumorganic compound particularly preferred temperatures during the addition are in the range from -30°C to -15°C. All foregoing reactions may be performed in air though the execution under inert gas atmosphere is preferred. Argon and nitrogen are preferred inert gases. The metalation and/or coupling reaction may also be carried out in microreactors and/or micromixers which enable high exchange rates; for example analogously to the processes 1 described in WO 2004/076470. Suitable solvents for the addition of the metalated compound VI to the appropriately protected gluconolactone IV are e.g. diethylether, toluene, methylene chloride, hexane, tetrahydrofuran, dioxane, N-methylpyrrolidone and mixtures thereof. The addition reactions may be carried out without any further adjuvants or in the presence of a promoter such as e.g. BF3*OEt2 or Me3SiCI which may be advantageous in the case of sluggishly reacting coupling partners (see M. Schlosser, Organometallics in Synthesis, John Wiley & Sons, Chichester/New York/Brisbane/Toronto/Singapore, 1994). Preferred definitions of the substituents R2 in Scheme 2a are benzyl, substituted benzyl, trialkylsilyl, particularly preferably tri-(C1-3-alkyl)silyl, such as trimethylsiiyl, triisopropylsilyl, 4-methoxybenzyl and benzyl. If two adjacent substituents R2 are linked together, these two substituents are preferably part of a benzylideneacetal, 4-methoxybenzylideneacetal, isopropylketal or constitute a dioxane with 2,3-dimethoxy-butylene which is linked via the 2 and 3 positions of the butane with the adjacent oxygen atoms of the pyranose. The group R' preferably denotes hydrogen, C1.4-alkyl, C1-4-alkylcarbonyl or C1-4-alkyloxycarbonyl, particularly preferably hydrogen, methyl or ethyl. The group R' is introduced after the addition of the organometallic compound VI or a derivative thereof to the gluconolactone IV. If R' equals hydrogen or Ci-alkyl the reaction solution is treated with an alcohol, in particular an C^-alkanol, such as e.g. methanol or ethanol or water in the presence of an acid such as e.g. acetic acid, methanesulfonic acid, toluenesulfonic acid, sulfuric acid, trifluoroacetic acid, or hydrochloric acid. This reaction with the alcohol or water is preferably carried out at temperatures in the range from about 0°C to 80°C, particularly from about 20°C to 60°C. During installing R' the protective groups R2 may be cleaved if labile under the reaction conditions employed resulting in the corresponding protonated compound, i.e. compound III in which R2 equals H. For example protecting groups wherein R2 denotes trialkylsilyl, such as trimethylsiiyl, are usually cleaved when the reaction solution is treated with an alcohol and/or water in the presence of an acid so that a compound III is obtained wherein R2 denotes H. R' may also be attached after preparation of the hydrogen compound III (R1 = H) by reacting the anomeric hydroxyl group with a suitable electrophile such as e.g. methyl iodide, dimethyl sulfate, ethyl iodide, diethyl sulfate, acetyl chloride, or acetic anhydride in the presence of a base such as e.g. triethlyamine, ethyldiisopropylamine, sodium or potassium or cesium carbonate, sodium or potassium or cesium hydroxide. The hydroxyl group can also be deprotonated prior to the addition of the electrophile with e.g. sodium hydride. Scheme 2b: Synthesis of C-Glucosides - Approach 2 Approach 2 depicted in Scheme 2b illustrates the synthesis of the C-glucosides commencing with an appropriately protected D-glucal XXX (see Synlett2004, pp. 1235-1238; Org. Lett. 2003, 5, pp. 405-2408 and references quoted therein for analogous approaches). The protected D-glucal XXX is metallated to yield the D-glucal derivative XXXI wherein M denotes a lithium, magnesium, zinc, indium, boron, tin, silicon or chromium moiety; in particular lithium, magnesium halide, zinc halide, indium halide, boronic acid, boronic acid ester. Metalation of glucal XXX at C-1 may be accomplished by deprotonation with a strong base. Strong bases capable of deprotonating the glucal may be lithium bases such as e.g. n-butyl lithium, sec-butyl lithium or tert-butyl lithium. The C-1 lithiated glucal thus obtained may be transmetalated with different electrophilic metal sources delivering the corresponding C-1 metalated glucal derivative. Metal species suitable for the subsequent transformation, coupling with the aglycon moiety, are derived from e.g. lithium, magnesium, zinc, indium, boron, tin, silicon, and chromium. The transmetalation of the glucal compound from lithium to one of the metals mentioned may be conducted with the corresponding e.g. halides such as chloride, bromide and iodide, sulfonates such as e.g. trifluoromethanesulfonate, and alcoxides such as e.g. methoxide, ethoxide, propoxide and isopropoxide of the metal species to be introduced. Depending on the metal transmetalated to the metal may bear more than one glucal residue such as in the corresponding triglucal indium or diglucal zinc. The corresponding monoglucal substituted metal derivatives are employable as well. The metalation of glucal with a strong base, in particular a lithium base, is preferably performed in inert solvents such as e.g. tetrahydrofuran, ether, dioxane, dimethoxyethane, hexane, and toluene. Preferred temperatures are in the range between -80 °C and 50 °C. The transmetalation may be conducted in the same solvents depending on the electrophilic metal species in the same temperature range. Among the electrophilic metal species usable in the transmetalation the following are among the most appropriate: trialkylchlorostannane, tetrachlorostannane, trialkylchlorosilane, trialkoxychlorosilyl chloride or bromide, boron trichloride, trialkyl borates, dialkylchloroborane, indium trichloride, zinc chloride, triflate or bromide, magnesium chloride or bromide. This compilation is by no means meant to restrict the employable metal electrophiles to the ones mentioned but is supposed to give an idea of electrophiles that can be used. In the above and below described reactions the protecting groups R2 are preferably chosen in view of their stability under basic conditions, in particular the groups R2 independently of each other denote -SiRaRbRc, wherein two adjacent groups R2 may be linked with each other to form a bridging group SiRaRb, wherein Ra, Rb, Rc are defined as hereinbefore, preferably denote isopropyl. The metalated glucal derivative of the formula XXXI thus obtained may be coupled with the agylcon V wherein the group X denotes a leaving group, preferably selected from the group consisting of chlorine, bromine, iodine, sulfonate such as e.g. trifluoromethane-sulfonate, tosylate, benezenesulfonate, and mesylate, chlorosulfonate, sulfonic acid or salts thereof, hydroxycarbonyl or salts thereof, nitrile, and diazonium salts. The coupling reactions are preferably carried out in the presence of a transition metal catalyst such as e.g. salts, complexes or elemental modifications of palladium, copper, iron, and nickel. Complexes can be formed in situ or prior to the addition of the transition metal to the reaction mixture. The ligands in the complexes of the transition metal may be e.g. triarylphosphine, aryldialkyl-phosphine, trialkylphosphine, phosphite, 1,3-disubstituted dihydroimidazolium carbene, 1,3-disubstituted imidazolium carbene, and alkenes. The reaction is preferably carried out in an inert organic solvent or mixtures thereof. Suitable solvents may be e.g. tetrahydrofuran, dioxane, dimethoxyethane, hexane, toluene, benzene, dimethylformamide, dimethylacetamide, N-methylpyrrolidinone, acetone, ethyl acetate, water, methanol, ethanol, propanol, isopropanol, ethylene glycol, polyethylene glycol. The coupling reactions are preferably carried out between -80 °C and 180 °C, more preferably at -20 °C to 120 °C. The concluding synthetic step in Scheme 2b is the formal addition of water to the double bond in the glucal moiety. This process may be done by e.g. hydroboration that results in the formation of the 2-boron-2-desoxy glucose derivative that can be converted to the corresponding glucose compound by oxidation of the carbon-boron bond. Suitable boranes for the hydroboration are e.g. borane or ether, thioether or amine adducts thereof, alkylboranes or dialkylboranes such as e.g. hexylborane, thexylborane, diethylborane and 9-BBN, pinacolborane, catecholborane, halo or dihaloborane such as e.g. dichloroborane. The hydroboration may be conducted in e.g. tetrahydrofuran, hexane, cyclohexane, ether, toluene, benzene, dichloromethane. A preferred temperature range is between -50 °C and 150 °C, preferably between -20 °C and 50 °C. The oxidative cleavage of the carbon-boron bond may be performed with an oxidizing reagent such as e.g. hydrogen peroxide, tert-butyl hydrogen peroxide, sodium perborate, and trialkylamine N-oxide. Depending on the oxidizing reagent the reaction is advantageously carried out in the presence of a base such as e.g. sodium hydroxide. The reaction is preferably carried out in an inert organic solvent or mixtures thereof. Preferred solvents are selected from among tetrahydrofuran, water, alcohols, dioxane, diemethoxyethane, cyclohexane, hexane, toluene, dichloromethane and mixtures thereof. A preferred temperature range is between -30 to 150 °C, preferably between 0 to 110 °C. An alternative to the hydroboration in order to add water to the double bond is the combination of epoxidation or dihydroxylation of the double bond and reduction of the resultant anomeric carbon-oxygen bond. Suitable oxidizing reagents for the epoxidation are e.g. dimethyldioxirane, trifluordimethyldioxirane, 3-chloroperoxybenzoic acid, hydrogen peroxide and oxygen in the presence of a transition metal catalyst. Another suitable oxidizing agent is peroxomonosulfuric acid, peroxodisulfuric acid and salts thereof, in the presence of at least one ketone, in particular triple salts of the formula 2 KHSO5 * KHSO4 * K2SO4 which are commercially available, for example under the brand names OXONE® (trademark E.I. du Pont de Nemours) and CAROAT® (trademark Degussa, Peroxid-Chemie GmbH & Co. KG, Dr.-Gustav-Adolph-Str. 3, D-82049 Pullach, Germany) in combination with a ketone, preferably acetone. Dihydroxylation can be accomplished with e.g. osmium tetroxide and dipotassium osmium tetroxide preferably in the presence of a co-oxidant such as e.g. potassium hexacyano-ferrate, hydrogenperoxide, and N-methylmorpholine N-oxide; hydrolytic opening of the oxirane resulting from the epoxidation gives also access to the dihydroxylation product. The oxidations may be conducted in inert organic solvents or mixtures thereof such as e.g. dichloromethane, tetrahydrofuran, ether, hexane, cyclohexane, dioxane, acetone, ethyl acetate, acetonitrile, water, alcohols and mixtures thereof. A preferred temperature range is between -80 °C and 100 °C, preferably between -50 °C and 50 °C. Reduction of the anomeric carbon-oxygen bond of the oxirane or dihydroxylation product may be accomplished with reducing agents such as e.g. trialkylsilanes such as e.g. triethylsilane, borohydrides such as e.g. sodium borohydride and aluminum hydrides such as e.g. diisobutylaluminum hydride. Depending on the reducing agent the presence of a Lewis acid such as e.g. boron trifluoride etherate, zinc chlorides, trimethylsilyl chloride or triflate, alkyl-, dialkyl- or aluminum halide, copper triflate, and Bronsted acids such as e.g. hydrochloric acid, acetic acid, alkyl- or arylsulfonic acids, trifluoroacetic acid is necessary or at least advantageous. Dichloromethane, acetonitrile, tetrahydrofuran, ether, hexane are among the preferred solvents. A preferred temperature range is between -80 °C and 120 °C. Hydrogen in combination with a transition metal catalyst such as e.g. palladium on carbon, Raney-nickel, and palladium hydroxide may be used as well. Subsequently, the product of the formula XXXIII may be transferred into the product of the formula I by cleaving, in particular hydrolysing, the protective groups R2 not being hydrogen, advantageously employing methods as described hereinbefore. Scheme 2c: Synthesis of C-Glucosides -Approach 3(Formula Removed) Scheme 2c illustrates an alternative access to C-glucosides starting from the glucal XXX (see e.g. Syn/eff 2003, pp. 870-872; Tetrahedron 2002, 58, pp. 1997-2009 and references quoted therein for analogous approaches). Epoxidation with an appropriate oxidizing reagent transforms the glucal XXX into the corresponding glucaloxide XXXIV. Suitable reaction conditions for this transformation have already been described for the analogous conversion of glucal XXXII shown in Scheme 2b. Among the oxidizing agents described there dimethyldioxirane and trifluorodimethyldioxirane generated separately or in situ are preferred. Said oxidizing agents may be obtained with e.g. peroxomonosulfuric acid, peroxodisulfuric acid and salts thereof, in the presence of at least one ketone, in particular with triple salts of the formula 2 KHSO5 x KHSO4 * K2SO4 which are commercially available, for example under the brand names OXONE® (trademark E.I. du Pont de Nemours) and CAROAT® (trademark Degussa, Peroxid-Chemie GmbH & Co. KG, Dr.-Gustav-Adolph-Str. 3, D-82049 Pullach, Germany) in combination with a ketone, preferably acetone. The reaction is preferably carried out at temperatures in the range between -80 and 0 °C in an inert organic solvent or mixtures thereof. Preferred solvents are selected from the group consisting of dioxan, 1,2-dimethoxyethane, toluene, hexane, tetrahydrofuran, diethylether, dichloromethane and mixtures thereof. In the above and below described reactions the protecting groups R2 are preferably independently of each other selected from the group consisting of C^-alkylcarbonyl, d.4-alkyloxycarbonyl, arylmethyl and RaRbRcSi, wherein aryl, Ra, Rb and Rc are defined as hereinbefore. The ensuing reaction, epoxide opening with a metalated aglycon of the formula VI in which M denotes a lithium, magnesium, zinc, indium, aluminum or boron moiety, affords the desired C-glucoside. For this transformation the preferred meaning of M is lithium, magnesium halide, zinc halide, indium halide, aluminum halide, dialkylaluminum halide or boronic acid compound. The synthesis of the lithium or magnesium derivative of compound VI has been detailed in Scheme 2a, whereas the transmetalation of these compounds to one of the alternative metal species may be done in analogy to the transmetalation of the lithiated glucal to the same metal derivatives presented in Scheme 2b. The epoxide opening reaction may take place without an adjuvant or in the presence of a transition metal salt or complex such as e.g. copper cyanide or halide or in the presence of a Lewis acid such as e.g. borontrifluoride etherate or trimethylsilyl-chloride or triflate. Suitable inert solvents may be e.g. acetone, ether, tetrahydrofuran, acetonitrile, dichloromethane, toluene, hexane and mixtures thereof. A preferred temperature range is between -80 °C to 60 °C. Subsequently the product of the formula XXXIII may be transferred into the product of the formula I by cleaving, in particular hydrolysing, the protective groups R2 not being hydrogen, advantageously employing methods as described hereinbefore. Scheme 2d: Synthesis of C-Glucoside - Approach 4v(Formula Removed) Hal = F,CI, Br, OAc, OAlk A glucose derivative XXXV bearing a potential leaving group Hal at the anomeric carbon may be utilized as starting material for the coupling with a metalated aryl aglycon VI as well (see J. Carbohydr. Chem. 1994, 13, pp. 303-321 and references quoted therein for analogous approaches). Suitable leaving groups Hal may be halides, alcoxides, acyl groups such as carboxylates and carbonates; in particular F, Cl, Br, C1-3-alkylcarbonyloxy, C1-3-alkyloxy-carbonyloxy or C1-3-alkyloxy, such as e.g. Cl, Br, methoxide, acetate and methylcarbonate. Suitable metals M attached to the aryl part are e.g. lithium, magnesium as e.g. magnesium halide, zinc as e.g. zinc halide, indium as e.g. indium dihalide, boron as e.g. boronic acid or boronic acid ester. The preparation of these metalated aryl compounds from the corresponding halogenated aromats has been described in Scheme 2c. The substitution reactions can be run without or in the presence of an additional Lewis acid such as e.g. boron trifluoride etherate, trimethylsilyl chloride or triflate depending on the metal species and glucosyl donor employed. The reaction is preferably carried out in an inert organic solvents or mixtures thereof. The preferred solvent is preferably chosen in view of the metalated aglycon, glucosyl donor and adjuvants needed; the following solvents may be advantageous: tetrahydrofuran, dioxane, toluene, hexane, ether, N-methylpyrrolidinone, dimethylacetamide, dimethylformamide, acetonitrile, dichloromethane and mixtures thereof. The coupling reaction is usually conducted between -80 °C and 120 °C, preferably at -60°C to 60 °C. In the above and below described reactions the protecting groups R2 are preferably independently of each other selected from the group consisting of C1-4-alkylcarbonyl, C1-4 alkyloxycarbonyl, arylmethyl and RaRbRcSi, wherein aryl, Ra, Rb and Rc are defined as hereinbefore. Subsequently the product of the formula II may be transferred into the product of the formula I by cleaving, in particular hydrolysing, the protective groups R2 not being hydrogen, advantageously employing methods as described hereinbefore. The synthesis of haloaromatic compound V may be carried out using standard transformations in organic chemistry or at least methods known from the specialist literature in organic synthesis (see inter alia J. March, Advanced Organic Reactions, Reactions, Mechanisms, and Structure, 4th Edition, John Wiley & Sons, Chichester/New York/Brisbane/Toronto/Singapore, 1992 and literature cited therein). The synthesis strategies described in the following provide a demonstration of this, by way of example. In the following schemes X denotes bromine or iodine, Alk denotes C1-4-alkyl, R denotes C-1-4-alkyl, C1-4-alkoxy, CF3, aryl or aryl-C1-3-alkyl, wherein aryl-groups may be mono- or polysubstituted with L1; R1 is as defined hereinbefore; and L1 is as defined hereinbefore; unless indicated otherwise. Scheme 3 displays the synthesis of aglycon V starting from benzophenone derivative IX that can be prepared from a benzoic acid derivative and a phenylalkylether or a metalated phenylalkylether (see Schemes 5, 8, and 9). The first step is the cleavage of the ether moiety in compound IX that can be accomplished under neutral, acidic and basic conditions. Suitable acidic reagents for this transformation are e.g. boron trichloride or tribromide or triiodide, trimethylsilyl iodide, aluminum chloride or bromide, hydrobromic acid, hydrochloric acid, cerium chloride, trifluoroacetic acid, and trifluoromethylsulfonic acid that may be used in concert with a nucleophile such as e.g. metal halides such as e.g. sodium iodide, water, alkylthiols, thioanisole, and dialkylsulfides, that may scavenge the departing alkyl group. Depending on the acid used solvents selected from the group consisting of halogenated hydrocarbons, such as e.g. dichloromethane, chloroform or 1,2-dichloroethane, acetonitrile, toluene, hexane, acetic acid and combinations thereof are preferred. Reactions without additional solvent are also feasible. The reactions are generally carried out at -90 to 150 °C, preferably at -80 to 50°C. Cleavage under neutral or basic conditions can be done e.g. with metal thiolates such as e.g. sodium sulfide, sodium ethanethiolate, sodium trimethylsilyl-thiolate, potassium thiophenolate, sodium cyanide, and lithium iodide in solvents such as e.g. dimethylformamide, dimethylacetamide, 1,3-dimethyl-2-oxohexahydropyrimidine, N-methyl-pyrrolidone, tetrahydrofuran, collidine, and quinoline at temperatures between 0 and 250 °C, preferably at 50 to 180 °C. The second step outlined in Scheme 3 comprises the attachment of residue R1 to the phenolic oxygen of compound VIII. This transformation can be carried out under basic conditions as classical nucleophilic substitution reaction. Accordingly, the phenol is deprotonated by a base to from the corresponding phenolate. Suitable bases are e.g. group I or II metal salts, in particular carbonates, hydroxides, alkoholates such as e.g. methoxide, ethoxide or tertbutoxide, and metal hydrides such as e.g. sodium hydride. The reaction can be conducted in polar and non-polar solvents as well as without solvent, preferably in alcohols such as e.g. ethanol, isopropanol or butanol, acetone, water, dimethylformamide, dimethylacetamide, A/-methylpyrollidone, dimethylsulfoxide, tetrahydrofuran, dichloromethane and mixtures thereof. The phenolate obtained then is reacted with an electrophile of R1 at temperatures between 20 and 180 °C, preferably between 40 and 120 °C. Suitable electrophiles of R1 are e.g. halides, such as chlorides, bromides or iodides, alkylsulfonates such as e.g. methylsulfonate, trifluoromethanesulfonate, arylsulfonates such as e.g. 4-bromophenylsulfonate, 4-methylphenylsulfonate or phenylsulfonate. An alternative approach to attach R1 to the phenol VIII is the addition of the phenol VIII to a group R1 that bears an appropriately situated C=C double bond. This reaction may be conducted in the presence of a Br0nsted acid such as e.g. trifluoro-methanesulfonic acid, hydrochloric acid, sulfuric acid, or a transition metal catalysts such as e.g. platinum, ruthenium, palladium, or gold salts or complexes thereof; preferred salts are triflate, chloride, bromide and iodide (see e.g. Cai-Guang Yang and Chuang He; J. Am Chem. Soc. 2005, 727, and references quoted therein). The solvent most appropriate for the addition depends on the acid or transition metal that is employed. Solvents such as e.g. toluene, benzene, dichloromethane, 1,2-dichloroethane, acetonitrile, tetrahydrofuran, dimethylacetamide, A/-methylpyrrolidone, hexane, and ethyl acetate may be suited. The reaction is carried out at 0 to 200 °C, preferably at 20 to 140 °C. Scheme 3 concludes with the reduction of benzophenone VII to furnish aglycon V. Proper reducing agents for this conversion are e.g. silane such as e.g. Et3SiH and triisopropylsilane, borohydride such as e.g. NaBH4, and aluminum hydride such as e.g. LiAIH4 in the presence of a Lewis acid such as for example BF3*OEt2, tris(pentafluorophenyl)borane, trifluoroacetic acid, hydrochloric acid, aluminum chloride, or lnCI3. The reactions are preferably carried out in solvents such as e.g. halogenated hydrocarbons such as dichloromethane and 1,2-dichloroethane, toluene, benzene, hexane, acetonitrile and mixtures thereof at temperatures of -30 to 150 °C, preferably at 20 to 100 °C. Reductions with hydrogen in the presence of a transition metal catalyst such as e.g. Pd on charcoal are another possible method of synthesis but might be less suited here due to competing reduction processes in the rest of the molecule. Reductions according to Wolff-Kishner or variants thereof are also conceivable. Hence, the ketone is converted with hydrazine or a derivative thereof such as e.g. 1,2-bis(tert-butyldimethylsilyl)hydrazine into the hydrazone which breaks down under strongly basic reaction conditions and heating to liberate the diphenylmethane V and nitrogen. The reaction may be carried out in one pot or after isolation of the hydrazone or a derivative thereof in two separate reaction steps. Suitable bases include e.g. KOH, NaOH or KOtBu in solvents such as e.g. ethyleneglycol, toluene, DMSO, 2-(2-butoxyethoxy)ethanol ortert-butanol; solvent-free reactions are also possible. The reactions may be performed at temperatures between 20 and 250 °C, preferably between 80 and 200 °C. An alternative to the basic conditions of the Wolff-Kishner reduction is the Clemmensen reduction which takes place under acidic conditions, which may also be used here if no concurrent dehalogenation occurs. Scheme 3: Synthesis of Aglycon V - Approach 1(Formula Removed) Scheme 4 outlines a slightly different approach to the synthesis of aglycon V compared with Scheme 3. Nevertheless, the ether cleavage and the ensuing etherification delineated in Scheme 4 can principally be carried out under reaction conditions analogous to the synthesis described above with respect to the compounds VIII and VII. Scheme 4: Synthesis of Aglycon V - Approach 2 ,CI ^ ,OAIk ether cleavage XV XI etherification Scheme 5 describes the assembly of aglycon V starting from the known benzoyl chloride XII and phenylether derivative XIII. The first step, the preparation of benzophenone VII, can be characterized as Friedel-Crafts or Friedel-Crafts-type acylation, a well-known and widely used method in organic synthesis. In principal, the benzoyl chloride XII may be replaced by other benzoic acid derivatives such as e.g. benzoyl anhydrides, esters, or benzonitriles. This classic reaction has a wide substrate scope and is commonly carried out in the presence of a catalyst such as e.g. AICI3, FeCI3, iodine, iron, ZnCI2, sulfuric acid, or trifluoromethanesulfonic acid which is used in catalytic or stoichiometric amounts. The reactions are preferentially performed in chlorinated hydrocarbons such as e.g. dichloromethane or 1,2-dichloroethane, in hydrocarbons such as e.g. hexane at temperatures ranging from -30 to 140 °C, preferably at 30 to 100 °C. However, other solvents and solvent mixtures and also solvent-free reactions or reactions in a microwave oven are also possible. The second reaction step in Scheme 5 is analogous to the final reaction in Scheme 3 as described hereinbefore. Scheme 5: Synthesis of Aglycon V - Approach 3 , 1 >- V Scheme 6 illustrates an alternative synthesis of the aglycon V via a Friedel-Crafts-type alkylation of phenylether XIII with benzyl electrophile XIV (see Angew. Chem. 2005, 117, pp. 242-246 and Syn. Commun. 2004, 34, pp. 3161-3165 and references quoted therein). The reaction is commonly conducted in the presence of a catalyst, in particular of a Lewis acid such as e.g. scandium chloride, zinc chloride, aluminium chloride or boron trifluoride, of a Br0nsted acid such as e.g. sulfuric acid, hydrochloric acid or hydrogenfluoride, of a lanthanide salt such as e.g. cerium sulfate or ytterbium chloride, of an actinide salt, of a transition metal salt or of a complex such as e.g. lrCI3*nH2O, RhCI3*nH2O, H2[PtCI6]*6H2O or H2[PdCI6]*6H2O. The catalysts can be applied in stoichiometric or excess quantities though in many cases substoichometric or even catalytic amounts are sufficient. The reactions are usually carried out with an excess of aromatic compound XIII relating to the benzyl electrophile without solvent; though inert solvents such as e.g. halogenated hydrocarbons or hydrocarbons can be employed as well. The reaction is generally conducted at temperatures between 0 and 200 °C, preferably at 20 to 140 °C. Scheme 6: Synthesis of Aglycon V - Approach 4 (Formula Removed) Friedel-Crafts type alkylation Z1 = OH, OR, OCOR, Cl, Br, I, OCOOR, OSO2R, OPO(OR)2, The approach presented in Scheme 7 starts with the synthesis of phenylether XVI from monosubstituted phenol XV that can be conducted analogously to the synthesis of the etherification shown in Scheme 3. In the second step of Scheme 7 the residue Z2 is exchanged for a metal or substituted metal residue. Lithium or magnesium substituted aromatic compounds XVII may be prepared from chlorinated, brominated, or iodinated aromatic compounds XV in the same manner as for the metalated aglycon VI described in Scheme 2a. The corresponding boron substituted compound such as e.g. boronic acid, boronic acid ester, or dialkylarylborane is accessible from these metalated phenyl groups XVII by the reaction with an appropriate boron electrophile such as e.g. boronic acid ester, haloboronic acid ester, alkylbornic acid ester, dialkylboronic acid ester, trihaloborane, and derivatives thereof. In addition, the boronylated aromatic compound XVII may also be prepared from the corresponding chlorinated, brominated, iodinated, or pseudohalogenated such as e.g. trifluoromethanesulfonated and tosylated precursor and a diboron compound such e.g. bis(pinacolato)diboron and bis(neopentyl-glycolato)diboron, or a borane such as e.g. pinacolborane through a transition metal catalyzed reaction (see e.g. Tetrahedron Lett. 2003, p. 4895-4898 and references quoted therein). The transition metal is e.g. palladium that is employed as element, salt, or complex; common Pd sources are e.g. palladium on charcoal, palladium acetate, palladium chloride, palladium bromide, palladium dibenzylideneacetone that are used as such or in combination with a ligand such as e.g. phosphines such as e.g. tricyclohexylphosphine, triphenylphosphine, 1,1'-bis(diphenyl-phosphino)ferrocene, and tritolylphosphine, or phosphites or imidazolium salts such as 1,3-diaryl ordialkylimidazolium halides or pseudohalides or dihydroimidazolium salts. The resulting complex of the transition metal and the ligand may be prepared in situ or in a separate step. The reactions are preferably conducted in the presence of a base such as e.g. triethylamine, potassium acetate, potassium carbonate, potassium phosphate, sodium hydroxide, triethylamine or ethyldiisopropylamine, in solvents such as e.g. acetonitrile, tetrahydrofuran, dimethylsulfoxide, dimethylformamide, dimethylacetamide, A/-methyl-pyrrolidone, dioxane, toluene and mixtures thereof at 0 to 180 °C, preferably at 60 to 140 °C. The lithium or magnesium substituted phenyl compounds XVII add spontaneously to benzaldehyde XVIII furnishing diarylmethanol XIX. This reaction can be performed in solvents such as diethylether, tetrahydrofuran, toluene, dichloromethane, dioxane, hydrocarbons such as e.g. hexane and mixtures thereof at temperatures ranging from -100 to 20 °C, preferably at -80 at 0 °C. Aryl boronic acids XVII can be added to the benzaldehyde derivative XVIII by means of a rhodium catalyzed reaction furnishing the respective diarylmethanol XIX (see e.g. Adv. Synth. Catal. 2001, p. 343-350 and references quoted therein). The concluding step in Scheme 7 is the reduction of the diarylmethanol XIX to the aglycon V. Suitable reducing agents for this transformation are e.g. NaBH4, LiAIH4, iBu2AIH, Et3SiH, iPr3SiH or Ph2SiCIH. The reaction is usually carried out in the presence of a Lewis acid such as for example BF3*OEt2, trifluoroacetic acid, hydrochloric acid, lnCI3, or AICI3 in a solvent such as halogenated hydrocarbons such as e.g. dichloromethane or 1,2-dichloro-ethane, toluene, hydrocarbons such as e.g. hexane, acetonitrile or mixtures thereof at temperatures of -80 to 150 °C, preferably at -20 to 100 °C. Reductions with hydrogen in the presence of a transition metal catalyst such as e.g. Pd on charcoal are principally also possible though particular care has to be taken using this method to preserve full integrity of the rest of the molecule. Scheme 7: Synthesis of Aglycon V - Approach 5 (Formula Removed) M1 = Li, MgHal, ZnHal, lnHa!2, CrHal2, B(OH)2, BR2, CeHal2 77--- Hal, OSO?R, OSO?CF, Hal = Cl, Br, I The synthesis sketched in Scheme 8 begins with the addition of metalated phenylether derivative XXI to benzoic acid or a derivative thereof (XX) such as benzoic acid esters, benzoic acid anhydrides, benzamides such as e.g. of the Weinreb type, benzonitriles, or benzoyl chlorides to deliver the benzophenone VII. Lithium or magnesium derivatized phenylethers XXI can principally be added to benzamides, benzoic acid esters, benzoyl chlorides, benzoic acid anhydrides, and benzonitriles to give the desired benzophenone VII while only lithiated phenylethers react with benzoic acids to produce the same compound. The latter reaction can be carried out in e.g. tetrahydrofuran, dioxane, diethylether, benzene, toluene, hexane and mixtures thereof at -80 to 100 °C, preferably at -30 to 40 °C. Benzonitriles and benzamides such as e.g. the corresponding Weinreb-type amide or a close derivative thereof are preferentially reacted in tetrahydrofuran, dioxane, toluene, hexane, ether and mixtures thereof at temperatures ranging from -90 to 50 °C, preferably at -80 to 20 °C. Benzoyl chlorides or anhydrides and benzoic acid esters are commonly employed in inert solvents such as tetrahydrofuran, diethylether, toluene, dichloromethane, dioxane, hydrocarbons such as e.g. hexane or mixtures of them at low temperatures, preferably at -80 to 0 °C. To prevent double addition of the organometal compound to benzoyl chlorides, benzoyl anhydrides or benzoic acid esters to produce the corresponding alcohol the addition may superiorly carried out in the presence of a trapping reagent such as e.g. trimethylsilyl chloride. An alternative choice to prevent double addition in the cases mentioned may be transmetalation to a less reactive nucleophile XXI. Suitable metals are e.g. zinc, cerium, chromium, or indium that are introduced as e.g. chloride, bromide, iodide or pseudo halide salt such as e.g. trifluoromethanesulfonate to transmetalate the lithium or magnesium compound to give the corresponding less reactive, more selective metal compound XXI. The transmetalation is preferentially conducted in the solvent wherein the initial organometal compound is generated (see above) at temperatures of -90 to 0 °C. Transmetalation is not restricted to the metals mentioned and the boron derivatized compounds already described in Scheme 7 but can also furnish e.g. stannanes and silanes. Some of the transmetalated compounds react spontaneously with the corresponding benzoyl electrophile, particularly benzoyl chloride and anhydride, but the addition of a transition metal catalyst may be advantageous. In particular arylboronic acids, esters thereof, dialkylarylboranes, aryltrifluoroborates, stannanes, silanes, indium, chromium, and zinc derivatized compounds XXI couple with benzoyl chloride derivatives XX mediated by a transition metal such as e.g. palladium, copper, iron, nickel, that may be used as element or salt such as e.g. acetate, chloride, bromide, iodides, acetylacetonate, trifluoromethanesulfonate, and cyanide in combination with ligands such as e.g. phosphites, phosphines such as e.g. triphenylphosphine, tricyclohexylphoshine, tritolylphosphine, 1,3-substituted imidazolium or dihydroimidazolium compounds delivering diarylketones VII. The active transition metal species can be prepared prior to the addition to the coupling partners but also in the presence of the reaction partners in situ. Suitable solvents are e.g. dimethylformamide, dimethylacetamide, A/-methy I pyrrol idone, dimethylsulfoxide, dioxane, ether, hexane, toluene, tetrahydrofuran, dichloromethane or mixtures thereof that are preferably used at -50 to 150 °C, particularly preferably at 0 to 120 °C. The concluding conversion to get to the aglycon V has been detailed above and can be applied analogously here. Scheme 8: Synthesis of Aglycon V - Approach 6 (Formula Removed) Z3 = e.g. COOH, COOR, CONR2, CONROR, CN, COCI M2 = e.g. Li, MgHal, B(OH)2, BR2, SiR3, SnR3, CeHal2, lnHa!2, ZnHal Hal= l,Br, Cl According to the Scheme 9 the metalated aryl groups XXIII that can be synthesized as described above can also be reacted with benzyl electrophiles XXII such as e.g. benzyl chlorides, bromides, iodides, sulfonates, phosphonates, carbonates, or carboxylates affording diarylmethanes V. Lithium or magnesium derivatized phenyl compounds XXIII are reacted favorably (but not always necessarily) in the presence of a transition metal such as e.g. copper, iron, nickel, or palladium (see e.g. Org. Lett. 2001, 3, 2871-2874 and Tetrahedron Lett. 2004, p. 8225-8228 and references cited therein). Usable solvents are e.g. tetrahydrofuran, dioxane, toluene, dichloromethane, hexane, ether or mixtures thereof. The range of reaction temperature is from -90 to 20 °C, preferably from -80 to -20 °C. The transition metal can be employed as element such as e.g. on charcoal, as salt such as e.g. acetate, acetylacetonate, cyanide, chloride, bromide, iodide, trifluoromethanesulfonate, or as complex such as e.g. with dibenzylideneacetones, phosphites, phosphines such as e.g. triphenylphosphine, tricyclohexylphoshine, and tritolylphosphine, or with carbenes derived from e.g. 1,3-disubstituted imidazolium or dihydroimidazolium compounds. The active transition metal species can be prepared in situ in the presence of the reaction partners or prior to the addition to the coupling partners. Arylmetal compounds XXIII bearing e.g. boron, tin, silicon, zinc, indium, chromium residue are preferably used in combination with a transition metal catalyst. Suitable metal compounds of these types are e.g. boronic acids, boronic acid esters, dialkylboranes, trifluoroborates, trialkylstannanes, trichlorostannanes, trialkoxysilanes, dihaloindium substituted or halozinc substituted compounds. The metal substituted compounds XXIII may be synthesized as described before by transmetalation from the corresponding lithium or magnesium derivatized compounds or as in the case of zinc, chromium and indium also directly from the corresponding arylchloride, bromide or iodide by insertion of the elemental metal. The coupling reaction with the benzyl electrophile may be conducted in tetrahydrofuran, dimethylformamid, dimethylacetamid, /V-methyl-pyrrolidone, dimethylsulfoxide, toluene, ether, dioxane, dichloromethane, acetonitrile, hexane, water, alcohols such as e.g. ethanol, isopropanol, or mixtures thereof at reaction temperatures of-30 to 180 °C, preferably at 20 to 150 °C. Depending on the metal an additional base such as e.g. triethylamine, ethyldiisopropylamine, cesium or potassium or sodium or lithium carbonate, potassium or sodium or lithium terfbutoxide, potassium phosphate, potassium or cesium ortetrabutylammonium fluoride, sodium hydroxide, thallium hydroxide, sodium methoxide and/or other additives such as e.g. lithium chloride, silver salts such as e.g. carbonate or oxide, tetrabutylammonium bromide, and sodium bromide may be advantageous or even essential (e.g. M. Schlosser, Organometallics in Synthesis, John Wiley & Sons, Chichester/New York/Brisbane/Toronto, 1994 and references cited therein). 39 Scheme 9: Synthesis of Aglycon V - Approach 7 0 , V Z" = OR, OCOR, Cl, Br, I, OCOOR, OSO2R, OPO(OR)2, M3 = e.g. Li, MgHal, B(OH)2, BR2, BF3M4, SiR3, SnR3, CeHal2, lnHa!2, lnHa!2, ZnHal, CrHal2 Hal = I, Br, Cl M4 = K, Na, Li The Scheme 10 shows the access to aglycon V via intermediate XXVI that can be prepared according to Scheme 8. If Z5 represents halogen such as F, intermediate XXVI may alternatively be prepared by Friedel-Crafts-acylation according to scheme 5. Replacement of Z5 in compound XXVI by O-R1 may be achieved via different methods. In the cases in which Z5 preferably denotes fluorine, chlorine, iodine, trifluormethylsulfonate O-R1 may be attached according to a nucleophilic substitution on an aromatic ring in which R1-OH or an anion thereof replaces Z5 in an addition/elimination sequence. The reaction is usually conducted in solvents such as e.g. dimethylformamide, dimethylacetamide, dimethylsulfoxide, tetrahydrofuran, dioxane, terfbutanol, toluene, /V-methylpyrrolidone, water, alcohol or mixtures thereof in the presence of a base such as e.g. lithium or sodium or potassium terfbutoxide, sodium or potassium or cesium carbonate, sodium or potassium hydroxide, tripotassium phosphate, triethylamine, ethyldiisopropylamine, or diazabicycloundecene at temperatures ranging from 0 to 180 °C, preferably at 40 to 140 °C. R1-OH may also be used as solvent and may be deprotonated with e.g. sodium hydride or sodium to form the alkoxide prior the addition of compound XXVI. To enhance the nucleophilicity of R1-O-metal the addition of crown ethers such as e.g. 18-crown-6 may be useful. The coupling of isolatable intermediate XXVI and R1-OH may also be conducted in the presence of a transition metal salt or complex such as e.g. derived from Pd or Cu (Ullmann or Ullmann-type reaction). Here Z5 preferentially stands for iodine or trifluoromethansulfonate. The same solvents, bases, additives, and temperatures described for the uncatalyzed reaction may be used for the catalyzed reaction except for that the latter is preferably executed under an inert gas atmosphere such as argon or nitrogen. The catalyst is usually employed as element as such or on charcoal, as a salt such as e.g. chloride, bromide, acetate, cyanide, or as a complex with ligands such as e.g. phosphites, phosphines, dibenzylideneacetone, 1,3-disubstituted imidazole or dihydroimidazole carbenes. If Z5 denotes arylboronic acid or trifluoroborate R1- OH may be attached via a copper(ll) catalyzed reaction with a copper source such as e.g. copper(ll) acetate in the presence of a base such as e.g. triethylamine or pyridine in solvents such as e.g. tetrahydrofuran, dichloromethane, 1,2-dichloroethane, acteonitrile, dioxane, dimethylformamide, dimethylacetamide, and N-methylpyrrolidone. The reaction may be carried out with stoichiometric amounts of copper catalyst or in the presence of a co-oxidant such as e.g. oxygen, pyridine-N-oxide, or tetramethylpiperidineoxide with only catalytic amounts of the catalyst. Dry solvents and the presence of drying agents such as e.g. molecular sieves are advantageous (see e.g. Angew. Chem. 2003, 115, pp. 5558-5607 and references quoted therein).

The Scheme 11 and the following sections describe preferred conditions and embodiments of the seventh aspect of this invention. The assembly of aglycon V starts from the known benzoyl chloride XII and halobenzene XXVII. The substituent X preferably denotes a bromine or iodine atom. A preferred meaning of the substituent Z5 is a fluorine atom. The first step, the preparation of benzophenone XXVI, can be characterized as Friedel-Crafts or Friedel-Crafts-type acylation, a well-known method in organic synthesis. In principal, the benzoyl chloride XII may be replaced by other benzoic acid derivatives such as e.g. benzoyl anhydrides, esters, or benzonitriles. This reaction is advantageously carried out in the presence of a catalyst such as e.g. AICI3, FeCI3, iodine, iron, ZnCI2, sulfuric acid, or trifluoromethanesulfonic acid, all of which are used in catalytic or up to stoichiometric amounts. A preferred catalyst is AICI3. The reaction may be performed with or without additional solvents. Preferred additional solvents are chlorinated hydrocarbons such as e.g. dichloromethane or 1,2-dichloroethane, hydrocarbons such as e.g. hexane or mixtures thereof. According to a preferred embodiment the reaction is carried out using an excess of the halobenzene XXVII which additionally serves as a solvent. Preferred temperatures during the reaction range from -30 to 140 °C, preferably from 30 to 85 °C After completion of the reaction the reaction mixture may be quenched with water. Preferably the organic solvents are removed. The intermediate XXVI may be isolated, preferably by crystallization, for example from water. The second reaction step in Scheme 11 which is the replacement of Z5 by O-R1 is analogous to the second reaction step in Scheme 10 as described hereinbefore. According to a preferred embodiment O-R1 is attached according to a nucleophilic substitution on an aromatic ring in which R1-OH or an anion thereof replaces Z5 in an addition/elimination sequence. The reaction is advantageously conducted in a solvent such as e.g. dimethylformamide, dimethylacetamide, dimethylsulfoxide, tetrahydrofuran, dioxane, terfbutanol, toluene, heptane, A/-methylpyrrolidone, water, alcohol or a mixture thereof. Preferred solvents are selected from dimethylformamide, tetrahydrofuran and dimethylacetamide. This reaction is preferably carried out in the presence of a base such as alkali C^-alkoxides, alkali carbonates, alkali hydroxides, alkali phosphates, tri(d.3 alkyl)amines and other N-containing organic bases. Examples of preferred bases are lithium or sodium or potassium terfbutoxide, sodium or potassium or cesium carbonate, sodium or potassium hydroxide, tripotassium phosphate, triethylamine, ethyldiisopropylamine, sodium bis(trimethylsilyl)amide (NaHMDS), diazabicycloundecene (DBU), 1,4-diazabicyclo[2.2.2]octane (DABCO) or mixtures thereof. More preferred bases are selected from sodium or potassium terfbutoxide, sodium or potassium hydroxide, cesium carbonate, a mixture of cesium carbonate and potassium carbonate, or mixtures thereof. The amount of the base is preferably in the range from 1 to 5 mol base per mol of intermediate XXVI. In case the base is a carbonate, phosphate or mixtures thereof, the total amount of the base is more preferably in the range from 2 to 4 mol base, most preferably about 3 mol base per mol of intermediate XXVI. The reaction is preferably carried out at temperatures ranging from about -20 to 60 °C, more preferably from about -10 to 40 °C, even more preferably from about 0 to 30°C. The intermediate VII may be isolated from the reaction mixture, preferably by crystallization, for example from a mixture of ethanol and water. The synthetic route according to Scheme 11 concludes with the reduction of benzophenone VII to furnish aglycon V. Suitable reducing agents for this conversion are silanes, in particular tri(Ci_3-alkyl)silanes, such as e.g. triethylsilane, dimethylethylsilane and triisopropylsilane, borohydrides such as e.g. NaBH4, and aluminum hydrides such as e.g. LiAIH4 in the presence of a Lewis acid such as for example BF3*OEt2, tris(pentafluorophenyl)borane, trifluoroacetic acid, hydrochloric acid, aluminum chloride, or lnCI3. A particularly preferred reducing agent is Et3SiH in the presence of a Lewis acid such as for example BF3*OEt2. Another particularly preferred reducing agent is NaBH4 in the presence of a Lewis acid such as for example trifluoroacetic acid. The amount of the reducing agent, in particular of Et3SiH, is preferably from about 1 to 5 mol, even more preferably from about 2 to 4 mol, most preferably about 3 mol per mol of benzophenone VII. The amount of the Lewis acid, in particular of BF3*OEt2, is preferably from about 1 to 5 mol, even more preferably from about 1 to 3 mol per mol of benzophenone VII. The reduction reaction is preferably carried out in a solvent such as halogenated hydrocarbons, for example dichloromethane and 1,2-dichloroethane, toluene, benzene, hexane, acetonitrile and mixtures thereof. Preferably the reduction is performed at temperatures from about -30 to 100 °C, preferably from about -20 to 50 °C, even more preferably from about -10 to 25°C. The aglycon of the formula V may be isolated and purified or may be used in the synthesis of the final product of the formula I without further purification. Starting from the aglycon of the formula V the product of the formula I may be obtained using the methods as described hereinbefore, preferably using the methods depicted and described in Scheme 2a. Scheme 11: Synthesis of Aglycon V - Preferred embodiment Z5 Friedel-Crafts acylation x XII XXVII Z5 = F, Cl, I "O-R1" reduction Cl In the reactions described hereinbefore, any reactive group present such as ethynyl, hydroxy, amino, alkylamino or imino groups may be protected during the reaction by conventional protecting groups which are cleaved again after the reaction. For example, a protecting group for a hydroxy group may be a trimethylsilyl, acetyl, trityl, benzyl or tetrahydropyranyl group. Protecting groups for an amino, alkylamino or imino group may be, for example, a formyl, acetyl, trifluoroacetyl, ethoxycarbonyl, tert.butoxycarbonyl, benzyloxycarbonyl, benzyl, methoxybenzyl or 2,4-dimethoxybenzyl group. Moreover, the compounds and intermediates obtained may be resolved into their enantiome-rs and/or diastereomers, as mentioned hereinbefore. Thus, for example, cis/trans mixtures may be resolved into their cis and trans isomers, and compounds with at least one optically active carbon atom may be separated into their enantiomers. Thus, for example, the cis/trans mixtures may be resolved by chromatography into the cis and trans isomers thereof, the compounds and intermediates obtained which occur as racemates may be separated by methods known perse (cf. Allinger N. L. and Eliel E. L. in "Topics in Stereochemistry", Vol. 6, Wiley Interscience, 1971) into their optical antipodes and compounds or intermediates with at least 2 asymmetric carbon atoms may be resolved into their diastereomers on the basis of their physical-chemical differences using methods known perse, e.g. by chromatography and/or fractional crystallisation, and, if these compounds are obtained in racemic form, they may subsequently be resolved into the enantiomers as mentioned above. The enantiomers are preferably separated by column separation on chiral phases or by recrystallisation from an optically active solvent or by reacting with an optically active substance which forms salts or derivatives such as e.g. esters or amides with the racemic compound, particularly acids and the activated derivatives or alcohols thereof, and separating the diastereomeric mixture of salts or derivatives thus obtained, e.g. on the basis of their differences in solubility, whilst the free antipodes may be released from the pure diastereomeric salts or derivatives by the action of suitable agents. Optically active acids in common use are e.g. the D- and L-forms of tartaric acid or dibenzoyltartaric acid, di-o-tolyltartaric acid, malic acid, mandelic acid, camphorsulphonic acid, glutamic acid, aspartic acid or quinic acid. An optically active alcohol may be for example (+) or (-)-menthol and an optically active acyl group in amides, for example, may be a (+)-or (-)-menthyloxycarbonyl. Furthermore, the compounds and intermediates of the present invention may be converted into the salts thereof, particularly for pharmaceutical use into the physiologically acceptable salts with inorganic or organic acids. Acids which may be used for this purpose include for example hydrochloric acid, hydrobromic acid, sulphuric acid, methanesulphonic acid, phosphoric acid, fumaric acid, succinic acid, lactic acid, citric acid, tartaric acid or maleic acid. The compounds according to the invention are advantageously also obtainable using the methods described in the examples that follow, which may also be combined for this purpose with methods known to the skilled man from the literature, for example, particularly the methods described in WO 98/31697, WO 01/27128, WO 02/083066, WO 03/099836 and WO 2004/063209. In the foregoing and following text, H atoms of hydroxyl groups are not explicitly shown in every case in structural formulae. The Examples that follow are intended to illustrate the present invention without restricting it. In case the pressure is indicated in the unit "Torr", the corresponding values can be converted into SI units by using 1 torr = 133.322 Pa.
