Abstract

The reaction of cyanoacetic acid hydrazide with 4-ethoxyphenylisothiocyanate gave the thiosemicarbazide derivative (3). The latter underwent a series of heterocyclization reactions when it reacts with either α-halo compounds, thioglycolic acid, acetylacetone, cinnamonitrile, or o-hydroxy aldehydes
