Abstract:

This survey represents 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.
