The synthesis of a protected 1,2-bis(indolyl)ethylhydrazine bearing the full substitution pattern present in the unusual dimeric alkaloid montamine is described. A variant of the Mitsunobu reaction was used to incorporate directly the reduced azodicarboxylate into the tryptophol side chain. The resulting carbazate underwent alkylation to give the core structure of the natural product.
描述了在不常见的二聚生物碱生物胺中存在的具有完全取代模式的受保护的1,2-双(吲哚基)乙基肼的合成。使用Mitsunobu反应的变体将还原的偶氮二羧酸酯直接掺入胰多酚侧链中。将所得的氨基甲酸酯进行烷基化以得到天然产物的核心结构。
