Rhodium-Catalyzed 2-Methylthiolation Reaction of Thiazoles/Oxazoles Using 2-(Methylthio)thiazole
摘要:
RhH(PPh3)(4) and 1,3-bis(dicyclohexyl)phosphinopropane (dcypp) catalyze the 2-methylthiolation of oxazoles and thiazoles using 2-(methylthio)thiazole as a thiolating reagent. The methylthio transfer reaction is under equilibrium, and various 2-methylthiolated thiazoles and oxazoles were obtained in moderate to good yields by removing thiazole under refluxing o-dichlorobenzene.
