A three-component strategy for the synthesis of thiazoles and isothiazoles has been developed by employing enaminoesters, fluorodibromoiamides/ester, and sulfur. The thiazoles and isothiazoles were formed via two C-F bond cleavages along with the formation of new C-S, C-N, and N-S bonds. The strategy provides high selectivity for the synthesis of thiazoles/isothiazoles, which have vital applications in drug discovery and development.

A facile and rapid access to multi-substituted oxazoles has been achieved under mild reaction conditions in a short reaction time. Reaction of enamides 1 with [bis(trifluoroacetoxy)iodo]benzene (PIFA) in trifluoroethanol (TFE) at room temperature for 15?min afforded the desired oxazoles 2 in moderate to excellent yields (58–98%). A wide range of functional group tolerance has been observed for these transformations.
