The Aza-ene Reaction of Heterocyclic Ketene Aminals with 4-Phenyl-1,2,4-triazoline-3,5-dione

Abstract

Heterocyclic ketene aminals bearing a secondary enamine moiety underwent an efficient aza-ene reaction with 4-phenyl-1,2,4-triazoline-3,5-dione under very mild conditions, while no reaction was observed with their tertiary enamine analogues.
