multiglycosylation. This method was illustrated by the successful preparation of a tetraglucoside β (1−> 6) equipped with a propargylic linker, ready for conjugation by click chemistry, using overall 5.6 equiv of thioglycosyl donors. Compared to the reported supported solution syntheses of oligosaccharides; the separation here is not based on a specific label (transferring its solubility properties to whole molecules)
我们在此提出了一种基于多元醇多糖基化的寡糖溶液合成的替代方案。该方法通过成功制备配备炔丙基接头的四葡糖苷 β (1-> 6) 来说明,该接头可通过点击化学进行缀合,使用总体 5.6 equiv 的硫代糖基供体。与报道的寡糖支持溶液合成相比;这里的分离不是基于特定的标记(将其溶解度特性转移到整个分子),而是基于分子量的增加(从 1500 到 15,000),从而允许在空间排阻柱上进行简单的分离。此外,所提出的协议不需要任何水处理,并使用黄色示踪剂在没有 TLC 或检测器的情况下直观地跟踪分离。
