in the nucleobase of pyrazofurin poses a huge challenge to the conventional NTP synthetic methods. On the basis of a selective phosphorylation method and the P(V)-N activation strategy, the first chemical synthesis of pyrazofurin 5′-triphosphate (PTP) was accomplished, which will greatly facilitate the investigation on the interactions of viral RNA polymerases and PTP, an important cellular metabolite
