摘要：

Aziridines were prepared from alpha-iodocycloenones in very good yield. by a Michael addition/cyclisation (Gabriel-Cromwell) process employing a slight excess of primary amine and Cs2CO3 as base at 95degreesC. Using chiral amines it, was possible to prepare optically pure aziridines. The same method as also efficient for the synthesis of aziridines from acyclic alpha-halounsaturated compounds. 2-Oxoazabicycles reacted with several nucleophiles to afford alpha-heteroatom substituted cyclic enones in excellent yield.
