专利号:US-6380416-B2 优先权日:1997-06-13 标题:Asymmetric synthesis catalyzed by transition metal complexes with rigid chiral ligands 发明人:ZHANG XUMU 权利人:PENN STATE RES FOUND 摘要:This invention is to develop novel transition metal catalysts for the practical synthesis of important chiral molecules. The invention emphasizes asymmetric catalysis based on chiral bidentate phosphine ligands with cyclic ring structures which could be used to restrict conformational flexibility of the ligands and thus the efficiency of chiral transfer can be enhanced through the ligand rigidity.
专利号:US-10174008-B2 优先权日:2014-12-03 标题:Synthesis of cyclopropyl indoles and cyclohepta[B]indoles, pharmaceutical compositions containing them and method of using them 发明人:TANG WEIPING; LI XIAOXUN 权利人:WISCONSIN ALUMNI RES FOUND 摘要:Methods of making indole analogs using a rhodium-containing catalyst are described, along with methods of using the compounds to treat hyperglycemic, hyperlipidemic, or autoimmune disorders in mammals, and corresponding pharmaceutical compositions. Disclosed herein is a method of making indoles. The method comprises contacting a reactant of formula I wherein E is a protecting group, —SO2-Aryl, or —SO2-substituted-Aryl; and R and R2 are independently selected from the group consisting of hydrogen, halo, C1-C12-alkyl and aryl; with a rhodium(1)-containing catalyst.
专利号:US-5321139-A 优先权日:1991-05-03 标题 :Process for the enantioselective synthesis of 2(R)-benzylsuccinic acid monoamide derivatives 发明人:LERCH ULRICH; JENDRALLA HEINER; SEURING BERNHARD; HENNING RAINER 权利人:HOECHST AG 摘要:Two processes are described for the preparation of the optically pure compounds of formula 1: (1) in which R1 and R2 are e.g. alkyl, R3 and R4 are e.g. hydrogen and R5 is e.g. hydrogen. Both processes include, as key steps, the enantioselective hydrogenation of a C=C double bond and the regioselective formation of a dicarboxylic acid monoamide derivative. In one process a phenylitaconic acid derivative is asymmetrically hydrogenated to give an optically active (R)-benzylsuccinic acid which is then converted to a diester, said diester being converted to the monoamide compound of formula 1. In the second process, a phenylitaconic acid derivative is converted to its anhydride, and the anhydride is then converted to a monoamide which is then asymmetrically hydrogenated to give the compound of formula 1.
专利号:US-7495123-B2 优先权日:2004-04-05 标 题:Process for the preparation of enantiomerically enriched beta amino acid derivatives 发明人:XIAO YI; SUN YONGKUI; ROSNER THORSTEN; RIVERA NELO R; KRSKA SHANE W; CLAUSEN ANDREW M; ARMSTRONG III JOSEPH D; SPINDLER FELIX; MALAN CHRISTOPHE 权利人:SOLVIAS AG; MERCK & CO INC 摘要:The present invention relates to a process for the efficient preparation of enantiomerically enriched beta amino acid derivatives wherein the amino group is unprotected. The product chiral beta amino acid derivatives are useful in the asymmetric synthesis of biologically active molecules. The process comprises an enantioselective hydrogenation of an amine-unprotected prochiral beta-amino acrylic acid or derivative thereof in the presence of a rhodium metal precursor complexed with a chiral mono- or bisphosphine ligand.
