摘要：

Azomethine ylides, prepared from imidazolinium salts, undergo 1,3-dipolar cycloaddition with a variety of dipolarophiles to produce hexahydropyrrolo[1,2-a]imidazoles, which are reduced to pyrrolidines; with 2-chloroacrylonitrile as dipolarophile, pyrroles can be prepared from the cycloadducts by elimination. © 1990.
