Convenient Structural Diversity‐Guided Synthesis of Functionalized Sulfur‐Containing Heterocycles via α‐Substituted Cyanoacetamides

A convenient molecular diversity‐oriented synthesis of various functional sulfur‐containing heterocyclic scaffolds mainly including isothiazole, 2H‐1,3‐thiazine, and thiazolidine via different methods from α‐substituted cyanoacetamides is described. The target molecules have been identified on the basis of analytical spectral data, which may serve as useful structural subunits in the fields of drug discovery.
