An efficient process for the stereoselective production of (2S,4S)-2-[[(R)-hydroxy-(3R)-cyclic amin-3-yl]methyl]pyrrolidine-4-thiol or its salts, which are intermediates useful in producing carbapenem, by reacting a compound represented by general formula (I) (wherein R1 represents lower alkylsulfonyl, optionally substituted arylsulfonyl or alkylsilyl; and R2 represents an amino-protective group) with a compound represented by general formula (II), wherein R3 represents optionally substituted lower alkyl or aryl; X represents oxygen or sulfur; Y represents azido or nitro; and m is an integer of from 2 to 5.
一种立体选择性生产(2S,4S)-2-[[(R)-羟基-(3R)-环氨基-3-基]甲基]吡咯烷-4-硫醇或其盐的高效工艺,它们是用于生产碳青霉烯的中间体,其方法是使通式(I)代表的化合物(其中R1代表低级烷基磺酰基、任选取代的芳基磺酰基或烷基硅基,R2代表氨基保护基团)与通式(II)代表的化合物反应,其中R3代表任选取代的低级烷基或芳基;X代表氧或硫;Y代表叠氮基;其中 R3 代表任选取代的低级烷基或芳基;X 代表氧或硫;Y 代表叠氮或硝基;m 为 2 至 5 的整数。
