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.
本发明提供了一种高效、多功能的单步不对称合成方法,用于从单一起始物质合成2-取代
吡咯烷的任一对映异构体,产率高,对映选择性高。同时还提供了一种方法,用于不对称合成2-取代
哌啶的两个对映异构体,产率好,对映选择性优异。还通过选择还原剂有效地控制对映选择性。
