Synthesis of 2โSubstituted 1 HโBenz[e][1,4]oxazepinโ5โones An approach to the hitherto unknown class of 1Hโbenz[e][1,4]oxazepinโ5โones is given based on reduction and cyclization of appropriate acyclic orthoโnitro compounds as starting materials. Thus, some 2โsubstituted derivatives (3aโi) were syn
