A Convenient Synthesis of 1,4-Dihydro-4-oxopyridazinoquinoxalines by a Ring Transformation of 1,2-Diazepinoquinoxalines

The reaction of the 1,2-diazepinoquinoxalines 2a,b or 3a,b with N-bromosuccinimide/water resulted in ring transformation to give the 1,4-dihydro-4-oxopyridazinoquinoxalines 4a,b respectively.
