A. Kamal et al., SYNTHESIS OF PYRROLO[2,1-C][1,4]BENZODIAZEPINE ANTIBIOTICS VIA AZIDO REDUCTIVE CYCLIZATION WITH HMDST, Tetrahedron letters, 37(37), 1996, pp. 6803-6806
A new facile synthesis of pyrrolo[2,1-c][1,4]benzodiazepine (PBD) ring
system has been achieved by reductive cyclization of the azide employ
ing hexamethyldisilathiane (HMDST). The parent unsubstituted PBD and t
he natural product DC-81 have also been prepared in good overall yield
