A stereocontrolled synthesis of α-2′-deoxynucleosides has been achieved. Our synthetic strategy involves the use of a benzoyl group at the 2-position of arabinose as a directing group for Vorbrüggen glycosylation and a deoxygenation precursor.

arabinose, and xylose glycosylation precursors were synthesized bearing C2-esters capable of directing Vorbrüggen glycosylation. The key step is the regioselective deoxygenation of the desired hydroxyl group as either the benzoyl- or 3-(trifluoromethyl)benzoyl derivative. This deoxygenation is accomplished via a photoinduced electron-transfer (PET) mechanism using carbazole derivatives as the photosensitizer
