Nucleoside analogues containing a 1,3-dioxolane structure are suitable antiviral agents, particulary for the treatment of the HIV infections in mammals, especially humans. Examples of the nucleoside analogues include:
cis-2-acetoxymethyl-4-(thymin-1′-yl)-1,3,-dioxolane,
cis-2-hydroxymethyl-4-(thymin-1′-yl)-1,3-dioxolane,
cis-2-benzoyloxymethyl-4-(cytosin-1′-yl)-1,3-dioxolane, and
cis-2-hydroxymethyl-4-(cytosin-1′-yl)-1,3-dioxolane.
These compounds can be in the form of their racemates or their separate enantiomers.

By simple combination of water and sodiumiodide (NaI) with chlorotrimethylsilane (TMSCl), promotion of a Vorbrüggen glycosylation en route to essential HIV drugs emtricitabine (FTC) and lamivudine (3TC) is achieved. TMSCl–NaI in wet solvent (0.1 M water) activates a 1,3-oxathiolanyl acetate donor for N-glycosylation of silylated cytosine derivatives, leading to cis-oxathiolane products with up to
