Synthesis of new iboga-analogues, replacing the indole ring with a benzofuran moiety has been described. Starting materials are the suitably substituted benzofuran derivatives and have been synthesized by Pd-catalyzed reactions. The conversion of endo-6-methylcarboxylate substituted dehydroisoquinuclidine to exo-isomer, a key component of iboga-alkaloids has been achieved in the presence of NaOMe in
已经描述了新的伊博加类似物的合成,其用苯并呋喃部分取代了吲哚环。起始原料是适当取代的苯并呋喃衍生物,并已通过Pd催化反应合成。的转化率内-6-甲基羧酸取代dehydroisoquinuclidine到外型-异构体,iboga生物碱的一个关键组成部分已经在NaOMe的甲醇的存在下在回流条件下实现的。
