Direct and Stereoselective Synthesis of α-Linked 2-Deoxyglycosides

Abstract
α-Linked 2-deoxyglycosides were conveniently obtained by employing a glycosyl donor having a participating (S)-(phenylthiomethyl)benzyl moiety at C-6, whereas 2,6-dideoxy-α-glycosides could be prepared by BF3·Et2O-promoted activation of allyl glycosyl donors.
