The synthesis of a bicyclic sulfonium ion analogue of a naturally occurring indolizidine alkaloid, swainsonine, in which the bridgehead nitrogen atom is replaced by a sulfonium ion, has been achieved by a multistep synthesis starting from (2S,3S,4R)-2,3-dibenzyloxy-4-formaldehyde-thiolane. The synthetic strategy relies on the intramolecular displacement of a leaving group on a pendant acyclic chain
天然吲哚并立生物碱swainsonine的双环sulf离子类似物的合成,已通过(2 S,3 S,4 R)-开始的多步合成完成,其中桥头氮原子被sulf离子取代。2,3-二苄氧基-4-甲醛-硫杂环戊烷。合成策略依赖于环状硫醚在无环侧链上的离去基团的分子内置换。该双环sulf盐提供了一种候选物,可用来进一步探究带有永久性正电荷的sulf盐是有效的糖苷酶抑制剂的假说。
