摘要：
An efficient and environmental protocol for the synthesis of 3-aryl-2H-benzo[b][1,4]oxazin-2-ones under mild benign conditions has been developed. This facile one-pot approach to 3-aryl-2H-benzo[b][1,4]oxazin-2-ones from commercially available benzoxazoles and alpha-keto acids which only promoted by DIPEA. The protocol exhibits a wide range of applicability in terms of benzoxazoles and alpha-keto acids. Notably, the 2-aryl benzothiazoles can be produced under the similar reaction conditions.
