Abstract
A high-yielding and stereocontrolled construction of 2-azido-2-deoxy-1,2-trans-β-glycosidic linkages has been achieved by exploiting TMSOTf-promoted 1,2-trans-glycosidation of 2-azido-2-deoxyglycopyranosyl diphenyl phosphates with various glycoside alcohols in propionitrile at −78°C. The present method exhibits the highest levels of 1,2-trans-β-selectivity reported to date for this type of glycosidation.
