Catalyst-Free Intramolecular Oxidative Cyclization of N-Allylbenzamides: A New Route to 2,5-Substituted Oxazoles
摘要:
A catalyst-free intramolecular oxidative cyclization reaction of N-allylbenzamides has been developed to prepare 2,5-disubstituted oxazoles with good yields. This reaction gives an efficient synthetic strategy to form an oxazole nucleus directly from easily accessible substrates under temperate conditions.
