We synthesized D-1,3-dioxolanyl acetate from D-mannose using Frazer-Reide reaction and D-1,3-oxathiolanyl acetate from either D-mannose or D-galactose in good yields. These acetates were conjugated with various disilylated pyrimidine base using trimethylsilyl trifluoromethane sulfonate as a Lewis acid catalyst to obtain 32 different D-nucleosides.

(+/-)Dioxolane-T and(+/-)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(C1-C3) on 5 or 6 position.
D-1,3-디옥솔란 및 L-1,3-옥사티올란 5-페닐세레닐 피리미딘 뉴크레오사이드의 합성

Eight new D-1.3-dioxolanyl and L-1,3-oxathiolanyl nucleosides containing 5-phenyl- selenyl pyrimidine bases which are expected to have antiviral activity were synthesized. Condensation of D-1,3-dioxolane acetate and L-1,3-oxathiolane acetate with 5-phenylselenyl pyrimidines gave anomeric mixtures of their nucleosides which were separated by silicagel column chromatography.
