A variety of pyrrolo[3,4-b]hexahydro-1H-1,5-benzodiazepine derivatives have been prepared in a new one-pot reaction from thiophene-2,3-dione as well as pyrrolidinetrione derivatives and trans-(±)-1,2-diaminocyclohexane. The reactivity of 2,3-dicarbonyl fragment of thiophene-2,3-dione was exploited in the synthesis of fused quinoxaline systems.
