T. Szabo et al., 2-CYANOETHYL H-PHOSPHONATE - A REAGENT FOR THE MILD PREPARATION OF NUCLEOSIDE H-PHOSPHONATE MONOESTERS, Nucleosides & nucleotides, 14(3-5), 1995, pp. 715-716
2-Cyanoethyl H-phosphonate was condensed with protected nucleoside der
ivatives and the cyanoethyl group subsequently removed by anhydrous ba
se to give the corresponding nucleoside H-phosphonate in good yield.
