The synthesis of a bicyclic sulfonium-ion analogue of a naturally occurring glycosidase inhibitor, swainsonine, in which the bridgehead nitrogen atom is replaced by a sulfonium ion, has been achieved by a multi-step synthesis starting from 1,4-anhydro-2,3-di-O-benzyl-4-thio-D-lyxitol. The synthetic strategy relies on the intramolecular displacement of a leaving group on a pendant acyclic chain by a
天然存在的糖苷酶抑制剂swainsonine的双环sulf离子类似物的合成,其中桥头氮原子被replaced离子替代,它是通过从1,4-脱水-2开始的多步合成完成的, 3-二-O-苄基-4-硫代-D-木糖醇。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盐将用作候选者,以检验带有永久性正电荷的sulf盐将是一种有效的糖苷酶抑制剂的假说。
