Abstract

The stereocontrolled, de novo syntheses of β-2'-deoxy-, α-2'-deoxy-, β-3'-deoxy-, and β-2', 3'- dideoxyribonucleosides are described. Strategically protected ribose, 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 ...
