Three-Component Coupling–Oxidative Amidation–Heterocycloannulation: Synthesis of the Indole Alkaloids Hamacanthin A and trans-2,5-Bis(3′-Indolyl)piperazine
Concise and highly convergent syntheses of antifungal marine bis(indole) alkaloids, hamacanthin A and trans-2,5-bis(3′-indolyl)piperazine is described. The total synthesis of hamacanthin A is accomplished via the oxidative amidation–chemoselective heterocycloannulation of 2,2-dibromo-1-(1H-indol-3-yl)ethanone with 1-(1H-indol-3-yl)ethane-1,2-diamine. The reduction of desbromo hamacanthin with aluminum
描述了抗真菌海洋双(吲哚)生物碱、hamacanthin A 和反式-2,5-双(3'-吲哚基)哌嗪的简洁和高度收敛的合成。hamacanthin A 的全合成是通过 2,2-dibromo-1-(1H-indol-3-yl)ethanone 与 1-(1H-indol-3-yl)ethane-1 的氧化酰胺化-化学选择性杂环环化完成的, 2-二胺。用硼氢化铝还原 desbromo hamacanthin 得到生物碱反式-2,5-双(3'-吲哚基)哌嗪。还开发了两种新颖且方便的合成吲哚基-1,2-二氨基乙烷的方案,产率中等至良好。
