Abstract

A condensation of 2-aryl-3-(methylthio)acroleins (3a) -(3e), a new masked form of arylmalondialdehydes, with amidines yielded the corresponding 5-arylpyrimidines (4a)-(4k). Similarly, the reaction of 3 with N-substituted hydrazines gave the corresponding 1-substituted 4-arylpyrzolones (5a) - (5j).
