Reaction of benzylamine, anilines and nitrophenyl-, diphenylphosphinoyl-, and diphenoxyphosphinoylhydrazines with 5-aryl-4-acetyl-1-methyltetrahydropyrrole-2,3-diones regiospecifically involves the 4-acetyl carbonyl group. The tautomeric equilibrium in the condensation products is controlled by the nature of substituent in the nucleophilic component. The products of the reactions of 5-aryl-4-acetyl-1-methyltetrahydropyrrole-2,3-diones with primary amines and with nitrophenylhydrazines exist in crystal as ketoenamine and enehydrazone tautomers, respectively; the latter are stabilized by an intramolecular hydrogen bond. With diphenylphosphinoyl- and diphenoxyphosphinoylhydrazines, EE′E″ ketohydrazone tautomers.
