The facile synthesis of a series of 4-acyloxy-2-azabuta-1,3-dienes by the O-benzoylation and O-acetylation of the anions of the readily accessible monoimines of phenyl glyoxal, diacetyl, benzil, and 1-phenyl-propan-1,2-dione is described. This route provides easy access to 2-azabuta-1,3-dienes with substituents other than aryl groups on C-1, C-3, and C-4 of the diene skeleton.
