    摘要: A process for the preparation of 3'-substituted-2',3'-dideoxynucleosides and 2'-deoxynucleosides is provided that utilizes inexpensive, non-carbohydrate, acyclic, achiral starting materials and that proceeds with high enantiomeric and stereochemical control. The method can be used to prepare the pharmaceutically important compounds 3'-azido-3'-deoxythymidine, 3'-azido-2',3'-dideoxyuridine and 3'-fluoro-3'-deoxythymidine.

    摘要: A method and composition for the treatment of HIV and HBV infections in humans is disclosed that includes administering an effective amount of 2-hydroxymethyl-5-(5-fluorocytosin-1-yl)-1,3-oxathiolane, a pharmaceutically acceptable derivative thereof, including a 5′ or N4 alkylated or acylated derivative, or a pharmaceutically acceptable salt thereof, in a pharmaceutically acceptable carrier.A process for the resolution of a racemic mixture of nucleoside enantiomers is also disclosed that includes the step of exposing the racemic mixture to an enzyme that preferentially catalyzes a reaction in one of the enantiomers.
