Thiosemicarbazide reacts with cyclic anhydrides such as tetrahydrophthalic anhydride (I), benzalphthalide (V), β-(4-methoxyphenyl)glutaric anhydride (VII), 5-(4-chlorophenylhydrazono)-4-(4-methoxyphenyl)glutaconic anhydride (XII) and α-acetylhomophthalic anhydride (XIV) under different conditions to furnish a variety of fused heterocyclic systems like triazoloisoindoles (III and VI), oxazoloisoindole (IV), triazole (IX), triazolopiperidines (X and XI) and triazoloisoquinoline (XV).The compounds have been characterised on the basis of elemental analysis and spectral (IR, NMR) data.
