$({\pm})-Dioxolane-T$ and$({\pm})-BCH-189$ are know to possess anti-HIV activities, and less to xicities compared to other dideoxynucleoside AIDS drugs. We have synthesized 34 different enantiomerically pure nucleosides by glycosylation of L-1,3-dioxolanyl acetate and L-1,3-oxathiolanyl acetate sugar moieties with uracil or 6-azauracil with alkyl chains$(C_1-C_3)$ on 5 or 6 position.
