the replication of RNA viruses, including hepatitis C virus (HCV), the hitherto unknown 4′-C-azidomethyl-β-D-ribofuranosyl nucleosides of the five naturally occurring nucleic acid bases have been synthesized and their antiviral properties examined. These 4′-C-branched nucleosides were stereospecifically prepared by glycosylation of purine and pyrimidine aglycons with a suitable peracylated 4-C-azido
