Under homogeneous conditions, the silver(I)-catalysed cyclisation of the allenic amine derivatices (3a–c), thogh not (3d), is stereoselective giving cis-2,5-disubstituted pyrrolidines in high yield; cyclisation on (3a), using a heterogeneous silver(I)-catalyst, is nonstereoselective.
在均相条件下,银(I)催化的烯丙基胺衍生物(3a – c),而不是(3d)立体选择性,以高收率得到顺式-2,5-二取代的吡咯烷;使用非均相银(I)催化剂在(3a)上进行环化是非立体选择性的。
