1,2-Acyl migration to an electron-deficient nitrogen atom: a new rearrangement of diaziridines without ring opening
Abstract
5-Acyl-1,6-diazabicyclo[3.1.0]hexane (1) on treatment with t-butyl hypochlorite affords the corresponding N-chloro-derivative (2) which rearranges easily into 6-acyl-5-chloro-1,6-diazabicyclo[3.1.0]hexane (3) with a 1,2-shift of the acyl group.
