Efficient total synthesis of ibogaine, epiibogaine and their analogues has been described. An intramolecular reductive-Heck type cyclization was used for the construction of seven-membered indoloazepine ring to access iboga-skeleton. Larock’s heteroannulation reaction was employed for the creation of suitably substituted indole and Diels–Alder reaction was employed for the construction of the isoquinuclidine
已经描述了伊博加因,表艾博加因及其类似物的有效全合成。分子内还原性-Heck型环化用于构建七元吲哚并氮杂卓环以访问伊博加骨架。拉洛克(Larock)的杂环化反应用于生成适当取代的吲哚,而狄尔斯-阿尔德(Diels-Alder)反应用于构建iboga生物碱中的异喹核苷环。
