Thiocarbamoyl derivatives as synthons in heterocyclic synthesis

The synthetic utility of thiocarbamoyl derivatives is reported in a formal way. The title compounds are used as precursors for the synthesis of many heterocyclic rings. The reactions of the title compounds are subdivided into groups that cover reactions yielding monocyclic heterocycles e.g., pyrroles, thiophenes, pyrazoles, imidazoles, thiazoles, pyridines, pyrimidines, oxazines, and even fused heterocycles, e.g., thiazolopyrimidines and thiazolotriazines.
