The question of quasi-enamine reactivity of aminocyclopropanes. Rearrangement of isomeric 1-(morpholino)-7-chloro-7-phenylbicyclo[4,1,0]heptanes
Abstract
Comparison of the course of thermal rearrangement of isomeric chlorobicycloheptanes (1) and (2) reveals that the formation of products from (2) can be interpreted in terms of “quasi-enamine” reactivity.
