Abstract

Deprotonation with strong bases of N-vinyl ureas carrying an N′-aryl substituent leads to migration of the N′-aryl group from N to C via an allyllithium; with weaker bases and electron-deficient aryl rings the direction of the migration reverses, and aryl substituents α to the urea N atom may migrate from C to N.
