A facile procedure for the preparation of the imine form of the pyrrolo[2,1- c ][1,4]-benzodiazepine ring system by the oxidation of cyclic secondary amine with catalytic amounts of tetra-n-propylammonium perruthenate (TPAP) and N-methylmorpholine N-

A new facile synthesis of pyrrolo[2,1- c ][1,4]benzodiazepine (PBD) ring system has been achieved by reductive cyclization of the azide employing hexamethyldisilathiane (HMDST). The parent unsubstituted PBD and the natural product DC-81 have also bee
