Moreover, the invention relates to a process for the synthesis of organo-oxazaborolidine catalysts (organo-CBS) and of trialkylboroxins. Furthermore, the invention relates to methods of using dialkoxyorganoboranes for the preparation of organo-CBS catalysts and in Suzuki-type coupling reactions.
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.
