Abstract Dihydro-5H-dibenzo[b,g]azonine-6,13-dione (2) has been used as a precursor in the synthesis of the indolo[2,3-e]dibenzo[b,g]azonine and tribenzo[b,g,j][1,6]diazacyclododecine ring systems 6 and 7 respectively via a Fischer indolization/periodate oxidation sequence. Fischer indolization of the (1,4-phenylenedihydrazono) derivative 8 gave the polycyclic system 9. The Schmidt reaction of 2 led
摘要 Dihydro-5H-dibenzo[b,g]azonine-6,13-dione (2) 已被用作合成吲哚[2,3-e]dibenzo[b,g]azonine 和tribenzo[ b,g,j][1,6]二氮杂环十二烷环系统 6 和 7 分别通过 Fischer 吲哚化/高碘酸盐氧化序列。(1,4-苯二肼)衍生物8的Fischer吲哚化得到多环体系9。2的施密特反应导致苯并咪唑[1,2-b] [2]苯并氮杂环体系的形成11.曼尼希反应2 导致了螺环系统 15。2 与醛亚胺和芳香醛的反应也进行了研究。
