This invention relates to single enantiomers of novel cis-substituted 1,3-oxathiolanes, of the formula (I):
wherein;
R1 is hydrogen, and R2 is cytosine or 5-fluorocytosine;
and pharmaceutically acceptable salts and esters thereof.
This invention also relates to pharmaceutical compositions containing them and to the use of these compounds as antiviral agents, particularly in combination therapy.
