Stereoselective synthesis of the complete family of optically active dideoxygenated nucleosides of the apiose family have been developed. The chiral aldodiol system 7, a key intermediate in this synthesis, was prepared from the prochiral molecule 6, through the action of the lipase from Candida cylindracia. Approaches to novel enantiomeric and diastereoisomeric dideoxynucleosides containing the te

A chiral building block, (R)-2-(2,2-diethoxyethyl)-1,3-propanediol monoacetate was synthesized in high optical and chemical yields by lipase-catalyzed transesterification. From this compound, we synthesized chiral 3-substituted gamma-lactones and a new nucleoside with antiviral activity.

Short syntheticapproaches to opticallyactive, cis and trans dideoxynucleoside analogs of the D- and L-apiose family have been developed. The chiral precursor for the syntheses was the enzymatically prepared compound, S(-)-2-(2-propenyl)-1,3-propanediol monoacetate (5).
