Iodine(III)-promoted synthesis of oxazolines from N-allylamides
摘要:
PhI(OAc)(2) (activated by BF3 center dot OEt2) has been used to promote the oxidative cyclization of N-allylamides to give oxazolines. The reaction products are formed in high yield and, when a branched allylic amine is used, high diastereoselectivity. Initial mechanistic experiments suggest that the final C-O bond is formed from a reactive tight ion pair, rather than a neutral external nucleophile. (C) 2013 Elsevier Ltd. All rights reserved.
