One-pot synthesis of symmetrical P1,P2-dinucleoside-5′-diphosphates from nucleoside-5′-H-phosphonates: mechanistic insights into reaction path
摘要:
Six symmetrical P-1,P-2-dinucleoside-5'-diphosphates (Np(2)Ns) have been synthesized from nucleoside-5'-H-phosphonate monoesters via a one-pot reaction in high yields. The key sequential hydrolysis protocol was developed based on the observation of reactive P-1,P-2,P-3-trinucleoside-5'-triphosphate intermediate on P-31 NMR. (C) 2013 Elsevier Ltd.

Nucleoside5'-triphosphates (NTPs) play key roles in biology and medicine. However, these compounds are notoriously difficult to synthesize. We describe a one-pot method to prepare NTPs fromnucleoside5'-H-phosphonate monoesters via pyridinium phosphoramidates, and we used this approach to synthesize ATP, UTP, GTP, CTP, ribavirin-TP, and 6-methylpurine ribonucleoside-TP (6MePTP). Poliovirus RNA-dependent
and convenient synthetic protocols based on H-phosphonate chemistry have been developed for the preparation of nucleoside 5′-diphosphates. It consists of oxidation of the silylated H-phosphonate monoesters in pyridine with iodine to produce the corresponding N-pyridiniumphosphonate intermediates, followed by their reactions with orthophosphoric acid used as a nucleophile. The added value of the method
