Biomimetic total synthesis of (-)-mycoleptodiscin A (1) was achieved starting from the enantiopure key intermediate, which was prepared by Friedel-Crafts reaction between 7-methoxyindole and chiral primary allylic alcohol. The crucial step in this synthesis was an intramolecular Friedel-Crafts reaction at C-4 of the indole derivative driven by the EDG/EWG within a compound that was rationally designed
(-)-mycoleptodiscin A(1)的仿生全合成从对映纯关键中间体开始,该中间体是通过7-甲氧基吲哚与手性伯烯丙基醇之间的Friedel-Crafts反应制备的。该合成中的关键步骤是化合物中EDG / EWG驱动的吲哚衍生物在C-4处的分子内Friedel-Crafts反应,该化合物经过合理设计可防止在吲哚的C-2正电子上发生环化反应。提供1的完整碳骨架。这种吲哚衍生物在C-4的分子内Friedel-Crafts反应可用于合成其他C-4-取代的吲哚生物碱天然产物。
