The synthesis of the novel benzo[c]pyrrolo[1,2,3-ef][1,5]benzodiazepine ring system is described. This was achieved by cyclization of an appropriately substituted (7-aminoindolin-1-yl)benzamide or benzoic acid. The resulting tetracyclic lactams were reacted with N-methylpiperazine in the presence of titanium tetrachloride to provide derivatives which were tested for potential antipsychotic activity
描述了新型苯并[ c ]吡咯并[1,2,3- ef ] [1,5]苯并二氮杂ring环系统的合成。这是通过适当取代的(7-氨基吲哚-1-基)苯甲酰胺或苯甲酸环化来实现的。在四氯化钛的存在下,使所得的四环内酰胺与N-甲基哌嗪反应,以提供衍生物,并对其潜在的抗精神病活性进行了测试。
