7-Substituted norbornadienes were stereoselectively converted into the meso-3,5-bis(acetoxymethyl)cyclopentenes by a three-step sequence of ozonolysis, reduction, and acetylation. Rhizopus delemar lipase (RDL)-catalyzed asymmetric hydrolysis of meso-3,5-bis(acetoxymethyl)cyclopentenes afforded the monoalcohols of high enantiomeric purities (> 95% ee) in good yields (64-95%). The obtained monoalcohols 11 and 14 could be applied for the synthesis of antiviral carbocyclic nucleosides (-)-carbovir and (-)-BCA.

Amino acid esters of carbovir have been found to have improved bioavailability after oral administration compared with carbovir. The esters are particularly useful for the treatment of hepatitis B virus and retrovirus (e.g. human immunodeficiency virus) infections. A preferred amino acid ester is the valine ester.
