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.

Among 5-substituted cytosine analogues, 5-bromocytosine derivative (beta-isomer) 68 was found to be the most potent anti-HIVagent. In the case of purine derivatives, inosine analogue (beta-isomer) 78 was found to be the most potent anti-HIVagent in the 6-substituted purines and 2-amino-6-chloropurine derivative (beta-isomer) 90 showed the most potent activity in the 2,6-disubstituted purine series
