The complete tetracyclic core structure of plicamine, a novel Amaryllidaceae-type alkaloid, was expeditously prepared by a Ugi four-component condensation reaction, followed by a one-pot sequential phenolic oxidation and intramolecular coupling process. The employment of this strategy resulted in a rapid, formal synthesis of (±)-plicamine.
通过Ugi四组分缩合反应,然后一锅顺序酚氧化和分子内偶联过程,迅速制备了plicamine的完整四环核心结构(一种新型的芳科植物型生物碱)。该策略的采用导致了(±)-三聚氰胺的快速,正式合成。
