A Modular Approach to Access 1,4-Benzoxazinones, Spirooxazolidinones, and 4,1-Benzoxazepinones via Oxidative Aryl C-N Bond Formation Using Catalytic Hypervalent Iodine.

Herein, we present a highly efficient (one-pot) and unprecedented method for synthesizing 1,4-Benzoxazinones and 4,1-Benzoxazepinones under transition metal-free conditions through direct aryl C-H amination. For the first time, this work harnesses th…
