Aryl H-phosphonates. Part 13.1 A new, general entry to aryl nucleoside phosphate and aryl nucleoside phosphorothioate diesters
Abstract
The reaction of nucleoside H-phosphonate monoesters with phenols in the presence of a condensing agent, followed by oxidation of the in-situ-generated aryl nucleoside H-phosphonate diesters with iodine–water or with elemental sulfur, provides a new, ‘one-pot’, efficient entry to nucleoside phosphate or nucleoside phosphorothioate diesters bearing diverse aryl moieties.
