N-(2-Benzyloxycarbonyl)phenyl ketenimines undergo a thermally induced cyclization to give 2-substituted 4H-3,1-benzoxazin-4-ones. These processes involve the formation of a new carbon-oxygen bond and the migration of the benzyl group from the oxygen atom of the benzyloxy unit at the ester function to the terminal carbon atom of the ketenimine fragment.
