The synthesis of the new tricyclicsystem 5H-1,2,3-triazolo[5,1-c][1,4]benzodiazepine, diaza-analogue of 5H-pyrrolo[2,1-c][1,4]benzodiazepine, which is the common feature of some antitumor antibiotics, is reported. The structure of the new tricyclicsystem and of some of its key intermediates is assigned by means of a 13C nmr study.
新的三环系统5 H -1,2,3-triazolo [5,1- c ] [1,4]苯并二氮杂,、 5 H-吡咯并[2,1- c ] [1,4 ]的二氮杂类似物的合成据报道,]苯二氮卓是一些抗肿瘤抗生素的共同特征。通过13 C nmr研究确定了新的三环系统及其某些关键中间体的结构。
