Intramolecular insertion of cyclopropylidenes into N–H bonds and into C–H bonds adjacent to nitrogen
Abstract
Reaction of the amino-methyl-(V) and amino-ethyl-dibromocyclopropanes (IX, R3= H) with methyllithium leads to 3- and 2-azabicyclo[3.1.0]hexanes (VI) and (X) respectively in competition with the formation of allenes.
