    Ring Expansion of Oxyglycals. Synthesis and Conformational Analysis of Septanoside-Containing Trisaccharides
    摘要:
    Oxyglycals, derived from lactose and maltose, were expanded to trisaccharides through a ring expansion method. Trisaccharides with 6-7-5 and 6-7-6 ring sizes were prepared through the ring expansion method, with high diastereoselectivities, in each step of their synthesis. The NOE and ROESY NMR spectroscopies were used to assess the dipolar Couplings within the trisaccharide. A computational study was undertaken, from which low energy conformations, as well as, dihedral angles that define the glycosidic linkages were identified.

  • Straightforward synthesis of protected 2-hydroxyglycals by chlorination-dehydrochlorination of carbohydrate hemiacetals
    作者:Jan Choutka、Michal Kratochvíl、Jakub Zýka、Radek Pohl、Kamil Parkan

    日期:2020.10
    A straightforward and scalable method for the synthesis of protected 2-hydroxyglycals is described. The approach is based on the chlorination of carbohydrate-derived hemiacetals, followed by an elimination reaction to establish the glycal moiety. 1,2-dehydrochlorination reactions were studied on a range of glycosyl chlorides to provide suitable reaction conditions for this transformation.

    描述了一种用于合成受保护的 2-hydroxyglycals 的简单且可扩展的方法。该方法基于碳水化合物衍生的半缩醛的氯化,然后是消除反应以建立糖基部分。研究了一系列糖基氯的 1,2- 脱氯化氢反应,以为这种转化提供合适的反应条件。发现苄基醚、异亚丙基和亚苄基保护基团以及糖苷间连接与该协议兼容。所描述的方法操作简单,可以快速制备具有除酯保护基团以外的 2-羟基糖醛,为现有方法提供了可行的替代方案。
