efficient entry to nucleoside3′-H-phosphonoselenoate monoestersviaphosphinateintermediates was developed. It involves a reaction of suitably protected nucleosides with triethylammonium phosphinate in the presence of pivaloyl chloride, followed by selenization of the intermediatenucleosidephosphinates with triphenylphosphine selenide, to produce the corresponding nucleoside H-phosphonoselenoates
