We describe here an expedient and highly stereoselective procedure for the synthesis of alpha-glycosyl azides. Treatment of 1,6-anhydrosugars with trimethylsilyl azide in the presence of trimethylsilyl triflate led to the formation of alpha-glycosyl azides. All the reactions were highly stereoselective and afforded the alpha-glycosyl azides in good to excellent yields.
