摘要

Benzoxazinones represent a class of annulated nitrogen heterocycles that are of interest to organic synthesis owing to their various biological activities.[1] Among the different methodologies developed for their preparation,[2] cyclization of anthranilic acid, N- acylanthranilic acid, or isotonic anhydride are most accepted.[3] Although alternative methodologies are known,[4] the availability of substrates and required reaction ...
