    摘要： A cost-effective process scale method for preparing purine dioxolane nucleoside derivatives in racemic or optically pure form is disclosed, as are nucleoside derivatives prepared by the method. The method involves reacting a purine or a mono- or polysilylated purine derivative with an activated dioxolane analog to produce the dioxolane nucleoside analog in commercially useful yields. Direct reaction of purine or a mono- or polysilylated purine with dioxolanes takes place with highest reported chemical yields and excellent stereoselectivity when an additive in the form of an alpha cyano carbonyl compound or silylated alpha cyano carbonyl compounds is present in the reaction mixture during the glycosylation reaction.

    摘要： The present invention is directed to compounds, compositions and methods for treating or preventing viral infections using nucleoside analog monophosphate prodrugs. More specifically, HCV, Norovirus, Saporovirus, Dengue virus, Chikungunya virus and Yellow fever in human patients or other animal hosts. The compounds are certain 2,6-diamino 2-C-methyl purine nucleoside monophosphate prodrugs and modified prodrug analogs, and pharmaceutically acceptable, salts, prodrugs, and other derivatives thereof. In particular, the compounds show potent antiviral activity against HCV, Norovirus, Saporovirus, Dengue virus, Chikungunya virus and Yellow fever. This invention teaches how to modify the metabolic pathway of 2,6-diamino 2′-C-methyl purine and deliver nucleotide triphosphate(s) to polymerases at heretofore unobtainable therapeutically-relevant concentrations.
