A Decade of development of ethylidenethiosemicarbazides as building blocks for synthesis of azoles and azines (a review)

Abstract

This review represents the synthesis of ethylidenethiosemicarbazides, with aryl or heterocyclic moieties, and its utility as building blocks for construction of different heterocyclic compounds such as; thiazoles, thiazolidinones, [1,3,4]thiadiazoles, [1,3,4]triazoles, [1,3]thiazines, pyrimidines, thiazolo[5,4-b]quinoxalines, bis-thiazoles, and bis-pyrazoles. Also, the pharmaceutical applications of ethylidenethiosemicarbazides have been demonstrated.
