The invention provides methods and regents for the glycosylation of organic molecules. In one aspect, the invention provides a method for glycosylating a hydroxyl-containing organic compound (i.e., a glycosyl acceptor) comprising contacting a glycosyl donor with the hydroxyl-containing organic compound, in the presence of an oxidant, to yield a glycosylated organic compound. In certain embodiments, the methods provided herein provide glycosylation products with high anomeric selectivity. The methods can be applied to the synthesis of disaccharides, trisaccharides, polysaccharides, glycans, etc. Also provided herein are compounds (e.g., glycosyl donors and acceptors) which are useful building blocks in the provided reactions.
这项发明提供了一种用于有机分子的糖基化的方法和试剂。在一个方面,该发明提供了一种用于糖基化含有羟基的有机化合物(即糖基受体)的方法,包括将糖基供体与含有羟基的有机化合物在
氧化剂存在下接触,以产生糖基化的有机化合物。在某些实施例中,本文提供的方法提供了高各向异性选择性的糖基化产物。这些方法可以应用于二糖、三糖、
多糖、
糖类等的合成。本文还提供了在所述反应中有用的化合物(例如,糖基供体和受体),这些化合物是提供的反应中的构建模块。
