Simple method for the preparation of anhydrides of nucleoside-5'- monophosphoric acid and with 1-hydroxyethane-1,1-diylbis(phosphonic acid) has been developed.

Bis(dichlorophosphino)methane was converted to a β,γ-methylenetriphosphitylating reagent. The reagent was immobilized on aminomethyl polystyrene resin-bound linker of 4-acetoxy-3-phenylbenzyl alcohol to afford a polymer-bound β,γ-methylenetriphosphitylating reagent, which was reacted with unprotected nucleosides followed by oxidation with tert-butyl hydroperoxide, deprotection of cyanoethoxy groups with DBU, and acidic cleavage to produce 5′-O-β,γ-methylene triphosphate nucleosides in 53-82% overall yields. Among all the compounds, cytidine 5′-O-β,γ-methylenetriphosphate inhibited completely RNase H activity of HIV-1 reverse transcriptase at 700 μM.
4-nitrophenyl 4-morpholinylphosphonochloridate: a convenient reagent for the synthesis of ribonucleoside mono-, di- and tri-phosphates

The synthesis of the crystalline and easily accessible phosphorylating agent 4-nitrophenyl 7-morpholinylphosphonochloridate is reported.Its application to the preparation of 5'-phosphorylated ribonucleosides (e.g. pA, ppA and pppA) as well as RNA fragments (e.g. pUpU and ppUpU) is demonstrated.Further, special attention is paid to the mild removal of the 4-nitrophenyl group from fully protected phosphotriester intermediates.
