  Iodine(III)-Promoted Synthesis of Oxazoles through Oxidative Cyclization of N-Styrylbenzamides

  摘要：

  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.

  Room‐temperature azole C−H arylations were accomplished with inexpensive copper(I) compounds by means of photoinduced catalysis. The expedient copper catalysis set the stage for site‐selective C−H arylations of non‐aromatic oxazolines under mild reaction conditions, and provides step‐economical access to the alkaloid natural products balsoxin and texamine.

  An efficient synthesis of 2,5-disubstituted oxazoles via Co(III) catalysis is described herein. The synthesis is achieved under mild conditions through [3+2] cycloaddition of N-pivaloyloxyamides and alkynes. The reaction operates through an internal oxidation pathway and features a very broad substrate scope. The one-step synthesis of natural products such as texamine and balsoxin has been demonstrated
