Beckmann rearrangement of (E)-4-chromanone oxime, (E)-5-oximino-3,4- dihydro-1(2H)-benzoxepines, and (E)-5-oximino-3,4-dihydro-1(2H)-benzothiepine are catalyzed by InBr3 and AgOTf in refluxing acetonitrile resulting in the formation of pharmaceutically active heterocycles benzoxazepin-4-one, 5-oxo-benzoxazocines, and 5-oxo-benzothiazocine derivative, respectively, in excellent yield.
