The compound so prepared is useful as inhibitors of the enzyme HMG-CoA reductase and are thus used as hypolipidemic and hypocholesterolemic agents.
专利号:US-5463131-A 优先权日:1994-06-30 标题 :Synthesis of organohaloboranes and alkoxyorganoboranes 发明人:BURKHARDT ELIZABETH R 权利人:MINE SAFETY APPLIANCES CO 摘要:A one-step process is provided for the synthesis of organohaloboranes, including diisopinocampheylchloroborane, and alkoxyorganoboranes. The present process does not utilize a thermally unstable ether adduct or a malodorous dimethyl sulfide adduct as required in prior processes. In general, the organohaloboranes are synthesized in a single reactor by reacting olefin(s) and/or alkyne(s) with boron trihalide and diborane. Alkoxyorganoboranes are synthesized in a single reactor by reacting olefin(s) and/or alkyne(s) with alkylborate and diborane.
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.
