Original Paper


α-2-Deoxyglycosides were synthesized in ionic liquid ([bmim]BF4)by stereoselective glycosylation of endo-glycals with various o-nucleophiles in the presence of catalytic amount of pTSAin 71–95 % yield. High yields, easy recovery of the products, and reusable reaction medium (pTSA/IL couple) with consistent activity makes this protocol efficient and environmentally benign.
