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。
