Novel heterocyclic compounds were prepared by the reaction of 2-acetyl-2-oxopropylidene S,S-acetal with different amino compounds namely, hydrazine hydrate, phenylhydrazine, guanidine hydrochloride, thiosemicarbazide, o-phenylenediamine, o-aminophenol or o-aminothiophenol in different molar ratios.

Highly efficient and regioselective synthesis of 1-aryl-3,4-substituted/ annulated-5-(methylthio)-pyrazoles and 1-aryl-3-(methylthio)-4,5-substituted/ annulated pyrazoles has been reported via cyclocondensation of arylhydrazines with either α-oxoketene dithioacetals or β-oxodithioesters.
