The total syntheses of the potent antiviral agent (−)-macrolactin A (1) and two related family members, (+)-macrolactin E (5) and (−)-macrolactinic acid (7), have been achieved, exploiting a unified, convergent, and highly stereocontrolled strategy. Extensive use of the palladium-catalyzed Stille cross-coupling reaction for the stereospecific construction of the three isolated dienes including macrocyclization
强效抗病毒剂 (-)-macrolactin A (1) 和两个相关的家族成员 (+)-macrolactin E (5) 和 (-)-macrolactinic acid (7) 的全合成已经实现,利用统一的、收敛和高度立体控制的策略。广泛使用钯催化的 Stille 交叉偶联反应来构建三种分离的二烯(包括大环化),这是成功策略的基石。这些天然产物的全合成不再通过发酵获得,证实了它们的相对和绝对立体化学,并为进一步的生物学研究提供了可能的类似物。
