A full account of the concise total syntheses of dictyodendrins B and E, and the formal synthesis of dictyodendrin C are described. A palladium-catalysed Larock indole synthesis was used to form the highly substituted indole core, and a palladium-mediated one-pot consecutive Buchwald–Hartwig amination/C–H activation reaction was used to construct the key pyrrolo[2,3-c]carbazole core. Unsuccessful synthetic
描述了 dictyodendrin B 和 E 的简明全合成以及 dictyodendrin C 的正式合成。钯催化的 Larock 吲哚合成用于形成高度取代的吲哚核心,钯介导的一锅连续 Buchwald-Hartwig 胺化/C-H 活化反应用于构建关键的吡咯[2,3-c]咔唑核。还讨论了不成功的合成策略。
