Syntheses of 3b,4,6,7-Tetrahydro-5h,9h-pyrazino [2,1-c] phyrolo[1,2-a] [1,4] benzodiazepine, a valuable precursor of potential central nervous system agents
Two alternative routes to 3b,4,6,7-tetrahydro-4H,9H-pyrazino [2,1-c] pyrrolo [1,2-a][1,4] benzodiazepine, a useful intermediate for the synthesis of potential antidepressant agents, are described. Though following conceptually different synthetic approaches, both procedures lead to the title compound in a simple and profitable way.
