An efficient access to 2'-(dimethylamino)-2',3'-dideoxynucleosides is reported. The synthetic strategy relies on the 1,3-dipolar cycloaddition of C-alkoxycarbonyl nittones to allyl acetate, followed by reductive ring opening to substituted lactones, DIBALH reduction to the corresponding 3- (dimethylamino)tetrahydro-2-furanols, and coupling with silylated thymine. The removal of the dimethylamino group by Cope elimination affords a new formal synthesis of d4T and analogous unsaturated 2',3'-dideoxynucleosides.
