A general and efficient formal synthesis of pumiliotoxins and allopumiliotoxins has been achieved via a common key intermediate 3a. Our route featured a novel one-pot substitution–ring-opening sequence and an efficient Claisen-type condensation. This method is also applicable to quinolizidine derivative 2b.
通过通用的关键中间体3a,可以实现普通而有效的形式化pumiliotoxins和allopumiliotoxins的合成。我们的路线以新颖的一锅式取代-开环顺序和有效的克莱森型缩合为特色。该方法也适用于喹喔啉衍生物2b。
