method for the glycosylation of selenoglycosides activated by iodosylbenzene was developed. The glycosylation reaction conditions were mild, fast, and efficient, with a high tolerance to diverse protecting groups and a wide substrate scope, which is advantageous for synthesizing complex glycosides. In addition, selenoglycosides were shown to be orthogonal to thioglycosides under the promotion of iodosylbenzene
开发了一种由碘酰苯激活的硒代糖苷糖基化的新方法。该糖基化反应条件温和、快速、高效,对多种保护基具有较高的耐受性,底物范围广,有利于合成复杂糖苷。此外,在碘酰苯的促进下,硒代糖苷与硫代糖苷具有正交性。值得注意的是,通过乙酰基保护的硒代糖苷获得了高产率的低反应性葡萄糖醛酸化反应产物。最后,β-(1→6)低聚糖的正交一锅合成证明了该方法在低聚糖合成中的有用性。
