Efficient one-pot synthesis of substituted diphenyl 1, 3-thiazole through multicomponent reaction by using green and efficient Iron-catalyst via Cross-Dehydrogenative Coupling(CDC)

A clean and efficient, multi-component strategy for the synthesis of biologically important trisubstituted thiazole via the reaction of readily available barbituric acid, acetophenone, and aryl thioamides is reported in the presence of FeCl₃.6H₂O / O₂(Air) in DMF solvent. The advantages of the present methodology include a one-pot reaction, environment-friendly approach, cost-effectiveness, broad substrate scope, operational simplicity, short reaction time, easy workup procedure, and high yields.
