A convenient palladium-catalyzed carbonylative synthesis of 2-aminbenzoxazinones from 2-bromoanilines and isocyanates.

Mon ami(ne)! A general and convenient methodology for 2-aminobenzoxazinone synthesis has been developed (see scheme). Readily available 2-bromoanilines and isocyanates were used as substrates and various products have been prepared in good yields. Notably, [Mo(CO)6] as a solid CO source was applied instead of gas.
