The present invention relates to a method of preparing the antiviral compounds 2'-deoxy-5-fluoro-3'thiacytidine (FTC) and various prodrug analogues of FTC from inexpensive precursors with the option of introducing functionality as needed; methods of using these compounds, particularly in the prevention and treatment of AIDS; and the compounds themselves. This synthetic route allows the stereoselective preparation of the biologically active isomer of these compounds and related compounds.

The present invention relates to a process for the biocatalyst-mediated enantioselective conversion of enantiomeric mixtures of hydrophobic esters uing a biphasic solvent system. More particularly, the present invention relates to the enzyme-mediated enantioselective synthesis of anti-viral compounds, such as 2-hydroxymethyl-5-(5-flurocytosin-1-yl)-1,3-oxathiolane (FTC) and its analogues, in a non-homogenous reaction system.
