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 been prepared in good overall yields.
吡咯并[2,1- c ] [1,4]苯并二氮杂(PBD)环系统的一种新的简便的合成已通过使用六甲基二硅噻吩(HMDST)对叠氮化物进行还原环化而实现。母体未取代的PBD和天然产物DC-81也已经以良好的总产率制备。
