Benzoxazinone and its derivatives are well-known as a broad-spectrum of physiological activities compounds. Herein we report a novel approach for the synthesis of benzoxazine derivatives via a N,O-bindentate directing assisted Pd-catalyzed intramolecular amination reactions. Various benzoxazinone derivatives are obtained in moderate to good yields. The directing group can be removed under mild condition, highlighting potential synthetic utility of this method.

Key words: C—H functionalization, palladium catalysis, phenoxyacetic acid, intramolecular amination
