摘要

2, 3-Disubstituted pyrrolidines are prepared by SmI2-promoted cyclization of α-amino radicals generated from N-(α-benzotriazolylalkyl) alkenylamines containing a C C bond activated by an electron withdrawing substituent. The diastereoselectivity of cyclization is moderate and depends on the nature of the substituent at the pyrrolidine 2-position.
