  • Synthesis of trisaccharide repeating unit of fucosylated chondroitin sulfate

    日期:——
    We described the chemical synthesis of a sulfated trisaccharide repeating unit of fucosylated chondroitin sulfate (FCS), which has significant anticoagulant activity. Well-functionalized monosaccharides were readily prepared, and highly efficient glycosylations using a common activator (NIS/TfOH) were also presented. The synthesized trisaccharide 4 could be used to extend oligosaccharide sequences

    A series of the derivatives of chondroitin sulfate E (CS-E) disaccharide repeating unit were prepared by postglycosylation–oxidation strategy. The strategy showed excellent performance in glycosylation both on the reactivity and stereoselectivity. Different protecting methodologies were used for the manipulation of disaccharide building blocks. Substitutes at C-4 of glucosyl donors mildly influenced
    通过糖基化-氧化策略制备了一系列硫酸软骨素E(CS-E)二糖重复单元的衍生物。该策略在反应性和立体选择性上均表现出优异的糖基化性能。不同的保护方法被用于操纵二糖结构单元。葡萄糖基供体的C-4取代基对糖基化有轻微影响。目前的合成为CS-E重复单元的制备提供了可行的方法。
  • Solvent‐Free Glycosylation from per‐ <i>O</i> ‐Acylated Donors Catalyzed by Methanesulfonic Acid
    作者:Serena Traboni、Emiliano Bedini、Alba Silipo、Giulia Vessella、Alfonso Iadonisi
    DOI:10.1002/ejoc.202101121
    日期:2021.11.8
    A novel glycosylation procedure has been developed, featuring extremely low cost as well as experimental and environmental advantages. It is based on the direct activation of per-O-acetylated (or benzoylated) sugars by 5 mol % of cheap and eco-friendly methanesulfonic acid, under air in the absence of any solvent. Several products, including non-trivial glycosides and disaccharides, can be quickly
