Bis‐thiourea Derivatives and Their Utility in Synthesis of Mono‐heterocyclic,Bis‐heterocyclic,and Fused Heterocyclic Systems

Bis‐thiourea derivatives have distinguished synthetic potentialities. They are interesting substrates for construction of various classes of heterocycles, such as thiazoles, thiadiazoles, imidazoles, bis‐thiazoles, bis‐thiadiazoles, and fused heterocyclic systems. The current review is concerned on disclosing the synthetic and research applications of bis‐thioureas that were reported in the literature during the last decade.
