An atom economical approach for the synthesis of substituted thiazoles starting from enamines and elemental sulfur through the C−H functionalization/C−S bond formation is described. Under the optimized conditions, various substituted enamines reacted smoothly with elemental sulfur and the desired substituted thiazoles were generated in moderate to excellent yields.

The reaction of 3,5-diphenyl-1,2,4-dithiazol-1-ium perchlorate with several kinds of active methylenes gives a number of heterocycles, such as 4-hydroxy and 4-mercaptopyrimidine, pyrimidinone, and thiazole derivatives. On treatment with hydroxylamine-O-sulfonic acid, the 4-mercaptopyrimidines lead to the aminothio compounds or the isothiazolo[5,4-d]pyrimidine.
