This manuscript describes a highly enantioselective oxidative cyclization of N-Allyl Benzamides and derivatives thereof. This method uses a chiral triazole-based iodine catalyst to generate a hypervalent iodine compound in situ as the active catalytic species. Besides oxazolines, other N-heterocylces such as thiazolines, imidazolines as well as oxanines can be generated in high optical purities. <br>
