Stereoselective methods for the chemical synthesis of beta-N-glycosyl amides are needed to generate glycopeptides and glycoproteins. Here, we report that the Staudingerligation can be used to form glycosylated asparagine derivatives. The reaction proceeds with high stereoselectivity, and a variety of glycosylazides can function as substrates. Our results provide precedence for the use of this powerful
