studied. The conformational preferences and relative energies of the exo- and endocyclic alkenesulfonic acids obtained were analysed by high-temperature molecular dynamics and DFT calculations. Thioglycosides bearing a sulfonatomethyl moiety at the secondary position have been prepared for the first time. Finally, the attempted synthesis of 2-sulfonatomethyl glucoside by nucleophilic substitution reaction
已经研究了 Horner-Wadsworth-Emmons 烯化在正交保护的 O-和 S-糖苷的 2-和 3-位引入磺化甲基部分的适用性。通过高温分子动力学和 DFT 计算分析了所获得的外环和内环烯烃
磺酸的构象偏好和相对能量。首次制备了在二级位置带有磺化甲基部分的
硫糖苷。最后,还描述了通过亲核取代反应合成 2-磺基
甲基葡萄糖苷的尝试。
