Heterocyclic synthesis with 4-benzoyl-1-cyanoacetylthiosemicarbazide: Selective synthesis of some thiazole, triazole, thiadiazine, pyrrylthiazole, and pyrazolo[1,5-a]triazine derivatives
4-Benzoyl-1-cyanoacetylthiosemicarbazide undergoes coupling reaction with aromatic diazonium chloride to afford (arylhydrazono)thiosemicarbazide, which was reacted with phenacyl bromide regioselectivity to afford the thiazoline. The (arylhydrazono)thiosem
