Synthesis of Inosine Polyphosphates from Inosine 5’-Phosphate

Treatment of inosine 5’-phosphate (IMP) with 2,2’-dithiodianiline/triphenylphosphine provided an efficient method for the synthesis of inosine 5′-phosphoropiperidate under mild conditions. Inosine 5’-triphosphate (ITP) and inosine 5′-diphosphate (IDP) were efficiently synthesized from inosine 5’-phosphoropiperidate via the activation P(V)—N bond by 4,5-dicyanoimidazole.
