Syntheses of both 2′-amino-2′-ethynyl guanosine and uridine, using an intramolecular aminohydroxylation reaction as the key step, are described. The corresponding 5′-O-triphosphates of the aforementioned nucleosides were obtained and the inhibitory activity was subsequently evaluated against the hepatitis C virus NS5B polymerase.
