Stereoselective methods for the chemical synthesis of beta-N-glycosyl amides are needed to generate glycopeptides and glycoproteins. Here, we report that the Staudinger ligation can be used to form glycosylated asparagine derivatives. The reaction proceeds with high stereoselectivity, and a variety of glycosyl azides can function as substrates. Our results provide precedence for the use of this powerful
需要化学合成β-N-糖基酰胺的立体选择方法来产生糖肽和糖蛋白。在这里,我们报告Staudinger连接可以用来形成糖基化的天冬酰胺衍生物。该反应以高的立体选择性进行,并且多种糖基叠氮化物可以用作底物。我们的结果为这种强大的酰胺键形成反应用于N-糖肽合成提供了先例。[反应:看文字]
