The synthesis of some derivatives of the novel heterocyclic ring system pyrido[3,4-d][1]benzazepine is reported. Thus, pyrido[3,4-d][1]benzazepin-7-one 6 was prepared by cyclisation of the Michael adduct 5 with ammonium ferric sulfate. Reaction of 6 with phosphorus pentasulfide gave the thiolactam 7, which after methylation and subsequent reaction with amines furnished the amidines 10.
报道了新型杂环系统吡啶并[3,4- d ] [1]苯并ze庚因的一些衍生物的合成。因此,吡啶并[3,4 d ] [1]苯并吖庚因-7-酮6用所述迈克尔的环化来制备加合物5硫酸铁铵。6与五硫化二磷反应生成硫内酰胺7,甲基化后与胺反应生成reaction 10。
