专利号:US-2012302756-A1 优先权日:2010-02-19 标 题 :Process for synthesis of 2-substituted pyrrolidines and piperadines 发明人:LELETI RAJENDER REDDY; LIU YUGANG; PRASHAD MAHAVIR 权利人:LELETI RAJENDER REDDY; LIU YUGANG; PRASHAD MAHAVIR 摘要:The present invention provides a highly efficient, versatile one-step process for asymmetric synthesis of either diastereomer of 2-substituted pyrrolidines from a single starting material with excellent yields and high diastereoselectivety. Also provided is a method for the asymmetric synthesis of both diastereomers of 2-substituted piperidines with good yields and excellent diastereoselectivety. Diasteroselectivity is controlled effectively by choice of reducing agent.
专利号:US-6025502-A 优先权日:1999-03-19 标题:Enantopselective synthesis of methyl phenidate 发明人:WINKLER JEFFREY DAVID; AXTEN JEFFREY M; KRIM LORI 权利人:UNIV PENNSYLVANIA 摘要:The invention relates to an enantioselective method of making methylphenidate and derivatives thereof. The method involves use of a rhodium catalyst, and selectively produces the D-enantiomer of the methylphenidate derivative in excess of the L-enantiomer thereof. Furthermore, the method selectively produces the threo-diastereomer in excess of the erythro-diastereomer. The method is thus suitable for synthesis of D-threo-methylphenidate (the biologically active form of this compound) and derivatives thereof.
