Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to a polymer-supported rhodium (II) catalyst and its application, which includes addition reaction to carbon-carbon multiple bond in α-diazocarbonyl compounds, insertion reaction to C—H and X—H(X═N, O, S, Se, Si and the like) bonds, or rearrangement and additional cyclization reaction thereof. The present invention contributes to an atom economy required in the field including organic synthesis and in other fields. 
       BACKGROUND OF THE INVENTION 
       [0002]    Rhodium (II) complex represented by Rh 2 (OAc) 4  easily decomposes α-diazocarbonyl compound under much milder condition than transition metals such as cupper and complex of transition metal, to generate rhodium (II) carbene intermediate, although its structure has not been proved. 
         [0003]    Carbene carbon in rhodium (II) carbene intermediate shows extremely high electrophilicity and there are various reactions based on the intermediate. The reaction includes, for example, addition to carbon-carbon multiple bond, insertion to C—H and X—H(X═N, O, S, Se, Si and the like) bonds or rearrangement and additional cyclization reaction triggered by ylide formation, etc. All of the above reactions are catalytic reactions and they are important reactions in synthetic chemistry because of simultaneous formation of carbon-carbon bond formation and generation of asymmetric carbon (Reference 1). 
         [0004]    Rh 2 (OAc) 4  may easily replace acetato, a bridging ligand, with various carboxylato and amidato by a ligand exchange reaction, and may synthesize rhodium(II) complexes with various characteristics. For example, Doyle et al. developed asymmetric amidato complex Rh 2 (5S-MEPY) 4 , Rh 2 (4S-MPPIM) 4  and the like with fixed asymmetric space (Reference 2). The present complex has high enantio selectivity in intramolecular C—H insertion reaction of α-diazoacetato or α-diazoacetamide and intramolecular cyclopropane formation reaction thereof. McKervey, Davies et al. developed rhodium (II) carboxylato complex, wherein allenesulfonylprolinato was incorporated in bridging ligand. Particularly, Rh 2 (S-DOSP) 4  developed by Davies et al. accomplished extremely high enantio selectivity in intermolecular C—H insertion reaction of phenyldiazoacetato or vinyldiazoacetato and intermolecular cyclopropane formation reaction thereof performed in hexane (Reference 3). 
         [0005]    The present inventors developed rhodium (II) carboxylato complex integrated with optically active N-phthaloylamino acid as a bridging ligand and reported intramolecular asymmetric C—H insertion reaction and asymmetric additional cyclization and rearrangement reaction via ylide formation by the use of various α-diazocarbonyl compounds as substrates (Reference 4). 
         [0006]    Asymmetric catalytic reaction by homogeneous transition metal complex has often difficulties in separation and purification between catalysts and products after the reaction. Particularly, the field including medications, cosmetics and foods necessitate to remove strictly heavy metal from products. Furthermore, there are economical problems in applying to large-scale synthesis, since the complex needs expensive ligands and metal. Consequently, development of removal method of metal complex or recoverable and reusable catalysts has been actively performed (Reference 5). 
         [0007]    One of the solution concerning removal, recovery and reuse of rhodium (II) complex includes supporting of rhodium (II) complex immobilized in insoluble solid-phase carriers. Use of solid-phase rhodium (II) complex enables theoretically easy separation from products, recovery and reuse of expensive rhodium complex, and prevention of metal from releasing. For example, Doyle et al. developed rhodium (II) amidato complex Rh 2 (S-PYCA) 4 , whose bridging ligand is pyrrolidinone-5(S)-caroxylato incorporated with soluble polyethylene. They are successful in reusing the complex several times maintaining good asymmetric yield in intramolecular asymmetric C—H insertion reaction of α-diazoacetato (Reference 6). Moreover, Davies et al. paid attention to the property of binuclear rhodium (II) complex, whose axial position is occupied by various Lewis basic axial ligands, and proposed a supporting method, wherein Rh 2 (S-DOSP) 4  and various rhodium (II) complexes are coordinated with pyridines on solid-phase. In intermolecular asymmetric C—H insertion reaction of phenyldiazoacetato, they found that solidified Rh 2 (S-DOSP) 4  catalyst showed catalytic activity and asymmetry discriminative ability similar to those by Rh 2 (S-DOSP) 4  alone (Reference 7). While, Biffis et al. developed a catalyst, wherein rhodium (II) perfluorocarboxylato complex is supported by silica gel incorporated with perfluoroalkyl chains, and accomplished recovery and reuse of the catalysts in silanization reaction of alcohols (Reference 8).

       Problems to be Solved by the Invention 
       [0016]    Much attention has been paid recently to the field of development of solid-phase rhodium (II) complex, which enables recovery and reuse of the catalyst. Although recovery and reuse of a rhodium complex is easy when using Rh 2 (S-PYCA) 4  as reported by Doyle et al., the catalyst based on rhodium (II) amidato complex with low catalytic activity has much lower catalytic activity and asymmetry discriminative ability than the master block catalyst due to the solid-phase-support. Additionally, the method of Davies and Biffs et al. cannot prevent metal complex from releasing, and catalytic activity thereof decreases with repeating use, because supporting of rhodium (II) complex in insoluble polymers is not by covalent bonding. Therefore there is a room for improving for all the reported cases. Particularly, the reaction using these catalysts is difficult at low temperature. 
         [0017]    The present inventors investigated the development of solid-phase catalyst, wherein insoluble polymer-supported rhodium (II) carboxylato complex incorporated optically active N-phthaloylamino acid as a bridging ligand, and shows high catalytic activity and asymmetry discrimination ability in many diazo decomposition reactions 
       Means to Solve the Problems 
       [0018]    As the result, the present inventors developed a method for preparing a novel insoluble polymer-supported rhodium (II) complex, which comprises a ligand exchange reaction between an insoluble polymer and a rhodium (II) carboxylato complex, wherein the insoluble polymer was prepared by a copolymerization reaction of (i) a styrene derivative with substituted carboxylic acid, (ii) a stylene, and (iii) a linear alkane with both ends substituted by vinylbenzyloxy groups, and accomplished the present invention.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0031]    The polymer-supported metal complex catalyst of the present invention can be prepared by the following procedures. 
         [0032]    In the beginning, polymer parts functioning as ligands are synthesized. The polymer is obtained by the copolymerization of the following monomers. 
         [0033]    (1) a coordinating monomer having the following general formula (chemical formula 2) 
         [0000]    
       
                 
         
             
             
         
       
     
         [0034]    wherein R 1  is a divalent hydrocarbon group, which may contain heteroatoms, preferably alkyl-2-(4′-alkyloxyphthalimidomethyl) group; 
         [0035]    X is an oxygen atom, a sulfur atom or a group represented by ═NR 5 , preferably oxygen, wherein R 5  is a hydrogen atom or an alkyl group, preferably a hydrogen atom. 
         [0036]    The carbons in the vinyl group may have substituents, wherein the substituents include alkyl group such as methyl group and alkyloxy groups at ca position. 
         [0037]    The coordinating monomer is, for example, N-4-[6-(4-vinylbenzyloxy) hexyl]oxyphthaloyl-(S)-tert-leucine, N-4-[6-(4-vinylbenzyloxy) hexyl]oxyphthaloyl-(S)-phenylalanine or 6-hexenoic acid and the like. 
         [0038]    (2) a hydrophobic monomer having the following general formulae (chemical formula 3): 
         [0000]    
       
                 
         
             
             
         
       
     
         [0039]    wherein R 2  is an aromatic group, preferably phenyl, α- or β-naphthyl group. 
         [0040]    The carbons in the vinyl group may have substituents. Such substituent includes a methyl group, an ethyl group, a phenyl group, a nethoxyl group and the like. 
         [0041]    The hydrophobic monomer is, for example, styrene, 4-methylstyrene, α-methylstyrene, β-methylstyrene, stilbene or vinylnaphthalene and the like. 
         [0042]    (3) a polymeric monomer having the following general formulae (chemical formula 4): 
         [0000]    
       
                 
         
             
             
         
       
     
         [0043]    wherein R 3  is a divalent hydrocarbon group, which may contain heteroatoms, preferably 4,4′-(1,3-propyrene-1,3-dioxymethyl)phenyl group. 
         [0044]    The carbons in the vinyl group may have substituents. Such substituents include methyl, ethyl, phenyl groups and the like. 
         [0045]    The polymeric monomer is preferably a monomer represented by the following formulae (chemical formula 6): 
         [0000]    
       
                 
         
             
             
         
       
     
         [0046]    wherein R 6  and R 7  are independently —O—, —S—, —NR 8 — or —PR 9 —, preferably —O— or —NR 8 —, wherein R 8  and R 9  are independently a hydrogen atom, an alkyl group, an aryl group or an acyl group, preferably an acetyl group or a phenyl group. The alkyl group is preferably an alkyl group with 1-3 carbon atoms, and the aryl group is preferably a phenyl group. 
         [0047]    o is an integer between 0 and 4, preferably 0 or 1; p is an integer between 1 and 12, preferably an integer between 3 and 8, more preferably an integer between 4 and 6; q is an integer between 0 and 4, preferably 0 or 1; and r is an integer between 0 and 20, preferably an integer 1 or 2. 
         [0048]    The polymeric monomers are exemplified by 1,3-bis (4-vinylbenzyloxy) propane, 1,4-bis(4-vinylbenzyloxy) butane or 1,4-divinylbenzene. 
         [0049]    The molar ratio (k:l:m) of coordinating monomer: hydrophobic 10 monomer: polymeric monomer in a synthesized polymer are determined in a way that k is 1 to 15% and m is more than 0 and equal to or less than 99% relative to k+1+m and 1 is the remainder. 
         [0050]    The solvents usable to the copolymerization reaction include alcohol solvents such as tert-butyl alcohol, isopropyl alcohol, ethanol and the like or hydrocarbon solvents such as toluene and the like. Tert-butyl alcohol is preferably used to obtain excellent results. 
         [0051]    The concentration range between 20 and 50% by weight is used, but a high concentration range as much as possible is preferable. Polymerization initiator used includes azobisisobutyronitrile, benzoyl peroxide, tert-butylhydroperoxide, hydrogen peroxide-ferrous (II) salt or hydrogen peroxide-triethylaluminum and the like. The reaction temperature is selected from the range between 0° C. and reflux temperature of a solvent, and preferably around at 70° C. 
         [0052]    The reaction time depends on the reaction temperature and the composition of monomers, and is selected suitably from the time range between 1 and 96 hr. 
         [0053]    When N-4-[6-(4-vinylbenzyloxy)hexyl]oxyphthaloyl-(S)-tert-leucine, styrene and 1,3-bis(4-vinylbenzyl oxy) propane were copolymerized, functional group (carboxyl group in this case), which will become ligands, can be introduced in the inside of polymers and also produced polymers show high motility similar to micro gels, by suitable control of solvent, reaction temperature and concentrations at the time of polymerization [Spanka, C.; Clapham, B.; Janda, K. D. J. Org. Chem. 2002, 67, 3045-3050]. In other words, when the ratio of N-4-[6-(4-vinylbenzyloxy) hexyl]oxyphthaloyl-(S)-tert-leucine to styrene is 5:93, space and mobility necessary for progress of ligand exchange reaction of rhodium complex in inside of the polymers can be ensured. Furthermore, introduction of cross-linking agent with high degree of freedom as 1,3-bis(4-vinylbenzyloxy) propane enables easy invasion of metal complex to the inside of polymers relative to polymer carriers represented by conventional Merrifield resins because of great swelling of the present insoluble polymers in a solvent, and thus leads to high incorporation rate of metal complexes in the present polymer carriers. Moreover, high swelling ability of the present solid phase-supported catalyst based on mobility and high degree of freedom of long chain linkers substituted for N-phthaloyl-(S)-tert-leucine portion on cross-linking agents and carriers accomplish not only reaction at low temperature, in which conventional solid catalysts cannot be subjected, but also durability to physical abrasion, which enables frequent usage. 
         [0054]    Then, the polymer-supported metal complex catalyst of the present invention is formed by ligand exchange between the polymer ligands and metal-containing complex with catalytic activity. 
         [0055]    The complex is represented by the following general formula (chemical formula 5): 
         [0000]      (R 4 CXO) n M 1 M 2    
         [0056]    wherein M 1  and M 2 , which may be identical to or different from the others, are selected from a group consisting of rhodium, palladium, ruthenium, rhenium, iron, nickel, cupper, platinum, bismuth, cobalt, chrome, molybdenum, and tungsten, preferably rhodium, ruthenium, chrome, molybdenum, tungsten or cupper. 
         [0057]    X is defined as above. 
         [0058]    R 4  is an alkyl group, an aryl group, an aralkyl group, an alkyloxy group or an alkylamino group, which may have substituents, preferably an alkyl group or aminoalkyl group. 
         [0059]    n is an integer between 2 and 4, which is determined by the valences of M 1  and M 2 . For example, when both M 1  and M 2  are rhodium (II), ruthenium (II) or cupper (II), n is equal to 4. 
         [0060]    The complex is preferably Rh 2 (S-PTTL) 4  or Rh 2 (O 2 CCH 3 ) 4 . 
         [0061]    The ligand exchange reaction is performed by heating the solution containing polymers and complex. Since the reaction is equilibrium reaction, solution containing unreacted rhodium (II) complex and isolated ligands is removed after heating for a specified time and remained solid phase-supported catalyst is washed by a solvent. After the above cycle is repeated several times as required, the solvent is removed under reduced pressure. 
         [0062]    The solvent used for the present reaction includes hydrocarbon solvents such as chlorobenzene, toluene, xylene and the like, and is preferably chlorobenzene. 
         [0063]    The temperature of the reaction is in the range between about 100° C. and boiling point of a solvent. 
         [0064]    The reaction time is selected by the extent of reaction for rhodium (II) complex and typically continues for 1 to 9 hr. Generally, the reaction solution is washed once after 9 hr reaction, and then added again with rhodium (II) complex followed by heating. The cycle is repeated 2 to 3 times. About 50% of carboxyl group in the polymers are coordinated to metal complex by the method. 
         [0065]    The polymer-supported metal complex catalyst of the present invention may be prepared by the following method. 
         [0066]    Namely, it is possible to synthesize the catalyst as the following way. First, ligand exchange is performed by heating (heating at 110 to 130° C. in high boiling point solvents such as chlorobenzene, toluene, xylene and the like) the equimolar mixture of complex and coordinating monomers (linker binding ligands). Then, side chains with suitable length (alkyl group, whose ends must be incorporated with vinylphenyl group, with or without substituents between the groups and the complex) are introduced to phenol hydroxyl groups. After that, hydrophobic monomers (styrene) and polymeric monomers (1,3-bis(4-vinylbenzyloxy) propane) are copolymerized. 
         [0067]    In this case, it is possible to copolymerize by vigorously stirring after mixing aqueous solution of gum arabic-salt with chlorobenzene solution containing complex-hydrophobic monomers (styrene)-polymeric monomers (1,3-bis(4-vinylbenzyloxy) propane) in addition to the previous polymerization method. In this case, it is possible to prepare beads catalyst with optional grain size. 
         [0068]    According to the above method, the yield in the step for preparing initial rhodium (II) complex is low (unreacted soluble rhodium complex Rh2(S-PTTL)4 is recoverable and reusable in principle). However, the advantage is on the fact that the structure of a metal complex can be checked until immediately before polymerization and that all the carboxyl groups contained in polymers could be coordinated to metal in principle (there are no isolated carboxyl groups in the polymer catalyst). 
         [0069]    As the result, it is possible to obtain the polymer-supported metal complex catalyst having the following formula (chemical formula 1): 
         [0000]    
       
                 
         
             
             
         
       
     
         [0070]    wherein R 1  to R 4 , X, k, l, m, n, M 1 , M 2  are defined as above. 
         [0071]    The polymer-supported metal complex catalyst of the present invention is effective to C—H insertion reaction; cyclopropanization; X—H insertion reaction (X is silica, oxygen, sulfur, or nitrogen); [2,3]-sigmatropy-rearrangement reaction of oxoniumylide, sulfoniumylide or ammoniumylide; [1,2]-rearrangement reaction of oxoniumuylide, sulfoniumylide or ammoniumylide; 1,3-dipolar cycloaddition reaction of carbonylylide, thiocarbonylylide or azomethine ylide; hydrogenation, hydrosilanization, hydroformylation or silylformylation reaction of alkene or alkyne; hydrosilanization of α, β-unsaturated carbonyl compound; Mukouyama-aldol reactionof silylenolether or silylketeneacetal with aldehyde; carbonilene reaction; or Diels-Alder reaction. 
         [0072]    These reaction may be performed in halogenated hydrocarbon solvent such as dichloromethane, 1,2-dichloroethane and chloroform; aromatic hydrocarbon solvent such as toluene, benzene, benzotrifluolide, xylene and the like; ether solvent such as ether, tetrahydroflane, methyl-tert-butylether, methylcyclopentylether and the like; ester solvent such as ethylacetate, methylacetate and the like; hydrocarbon solvent such as hexane, pentane and the like; alcohol solvent such as ethanol, methanol and the like; nitrile solvent such as acetonitrile, propionitrile and the like; and nitroalkane solvent such as nitromethane, nitroethane and the like. 
         [0073]    The temperature range, in which the present catalysts work, is between −78 and 130° C. and the most suitable temperature may be selected based on the types of reaction to be done and activity of substrates and reactants. 
         [0074]    In the reaction of the present catalyst, insoluble catalysts may be removed from reaction mixtures by filtration after stopping the reaction. After the catalysts are filtered off, they are washed with suitable organic solvents for several times, are freed from solvents under reduced pressure and may be reused. 
         [0075]    The present invention is illustrated in the following Examples, but these Examples are not intended to limit the scope of the present invention

         [0119]    A reaction that uses a rhodium catalyst of the present invention may yield results comparable to those obtained when using Rh 2 (S-PTTL) 4 , a mother complex type homogeneous asymmetric catalyst that also exhibits chemical selectivity, diasteroselectivity and enantioselectivity while realizing asymmetric reactions at temperatures as low as −78° C., hitherto unobserved with solid supported transition metal complexes. In addition, the catalyst is insoluble in water, ethanol, ethyl acetate, acetone, ether, hexane, toluene, dichloromethane and the like making catalyst recovery and reaction product purification easy to conduct. In addition, recovered catalysts can be reutilized without losing their efficiency. For example, the yield in the reaction shown above (Chemical formula 7, R 1 =hydrogen atom, R 2 =methyl group) was 85%, the chemical selectivity for the C—H insertion/alkene formation was 99:1 and the asymmetric yield was 94%. After the reaction, the catalyst was repeatedly recovered and reutilized. The yield after recycling continuously twenty times was 83%, the chemical selectivity for C—H insertion/alkene formation was &gt;99:1, the asymmetric yield was 94%, and almost no change was observed in yield and selectivity. The rhodium (II) catalyst of the present invention can be referred to as a catalyst that is extremely useful in asymmetric carbene reactions such as C—H insertion reactions and the like. 
       Example 4 
       [0120]    The rhodium catalyst prepared in Example 1 was used to conduct an intramolecular asymmetric C—H insertion reaction. Toluene was added to the insoluble rhodium (II) catalyst to swell the catalyst, and the catalyst was subsequently cooled to −60° C. An intramolecular C—H insertion reaction proceeded when a toluene solution of methyl 2-(2-benzyloxyphenyl)-2-diazoacetate, the reaction substrate, was added. Upon conclusion of the reaction, the supernatent solution was recovered through decantation and concentrated to yield a cyclic product. The residue was washed using ethyl acetate and the like and dried under reduced pressure, and the catalyst could be utilized again. 
         [0121]    The results are shown in the table below.

         [0122]    Asymmetric reactions were realized at temperatures as low as −60° C. in reactions that used a rhodium catalyst of the present invention. The reactions yielded results comparable to those obtained when using Rh 2 (S-PTTL) 4 , a mother complex type homogeneous asymmetric catalyst, as far as chemical selectivity, diasteroselectivity and enantioselectivity were concerned. The yields, the locations and diastereoselectivity and asymmetric yields remained unchanged when the rhodium catalyst of the present invention was repeatedly recycled fifteen times. The rhodium (II) catalyst of the present invention can be referred to as a catalyst that is extremely useful for substrates having diverse structures such as those described above.

       Example 7 
       [0133]    The recyclability of the catalyst of the invention in an intramolecular aromatic ring C—H insertion reaction was investigated in the present example. The catalyst of the invention was insoluble and could be removed from a reaction mixture using filtration upon conclusion of the reaction. After filtration the collected catalyst was washed several times using an appropriate organic solvent, and it could be utilized again after the solvent was removed using distillation under reduced pressure. No decline in reactivity and asymmetry identification capability was observed in the present example after the solid phase supported metal catalyst of the present invention was used repeatedly for one hundred times as described below. 
         [0134]    To a reaction test tube containing 7.4 mg of the solid phase supported rhodium (II) complex (2 mole % of the catalyst) obtained in Example 1 and 0.5 ml of methyl dichloromethane was added 0.5 ml of a dichloromethane solution containing 30.8 mg of methyl 2-diazo-4,4-diphenyl-3-oxopentanoate at room temperature. The reaction mixture was agitated for twenty minutes at the temperature. The supernatent solution was decanted, and the residue was subsequently washed using 1 ml of dichloromethane. The supernatent solution and washing were combined and concentrated to give 28 mg of a residue that was purified using column chromatography (1 g of silica gel, benzene) to obtain 24.1 mg of methyl (3S)-3-methyl-3-phenyl-2-oxoindane-1-carboxylate (86%) in the form of pale blue solids. The optical purity of the methyl (3S)-3-methyl-3-phenyl-2-oxyindane-1-carboxylate in the mixture was found to be 91% ee according to HPLC analysis. The recovered solid phase supported rhodium (II) complex was dried under reduced pressure and used repeatedly for the same reaction.

The reaction solution changed to pale orange. The solution was allowed to cool, 5 ml of water was added, and the solution was extracted using 20 ml of ethyl acetate. The organic layer was washed using 5 ml of saturated aqueous saline solution and was dried using anhydrous sodium sulfate. The solvent was removed by distillation under reduced pressure, and the residue obtained was purified using silica gel column chromatography (1 g, 1:2 hexane/benzene) to obtain 18.2 mg of (S)-3-methyl-3-phenyl-2-indanone (95%) in the form of a pale orange oily material. 
         [0138]    The analytical data for (S)-3-methyl-3-phenyl-2-indanone are shown below.
