studies with different glycosidase enzymes. The syntheses involved the reaction of isopropylidene-protected 1,4-thio- and 1,4-seleno-D-talitols and 1,5-thio- and 1,5-seleno-L-gulitols, derived from D-mannose, with a benzylidene- and isopropylidene-protected 1,3-cyclic sulfate, also derived from D-mannose. Deprotection of the products afforded the novel selenonium and sulfonium sulfates composed of heterocyclic
合成了四种天然糖苷酶抑制剂salacinol 的链延长类似物,用于不同糖苷酶的结构活性研究。合成涉及异丙叉保护的 1,4-硫代-和 1,4-硒-D-塔糖醇与衍生自 D-甘露糖的 1,5-硫代-和 1,5-硒-L-gulitols 与亚苄基和异亚丙基保护的 1,3- 环硫酸盐,也衍生自 D-甘露糖。产物的脱保护提供了由杂环五元和六元环核心结构组成的新型硒和锍硫酸盐,具有多羟基化的六碳原子无环链。 关键词:糖苷酶抑制剂,两性离子硒和锍硫酸盐,环硫酸盐
