The hypervalent iodine reagent PhI(OTf)(2), generated in situ, has been successfully utilized in an intramolecular oxidative cyclization of N-styrylbenzamides. In remarkably short reaction times, the desired 2,5-disubstituted oxazoles were isolated in high yields in this metal-free oxidative C-O bond-forming reaction.
