Mv. Jasko et al., A NEW APPROACH TO SYNTHESIS OF 5'-O-PHOSP HONOMETHYL DERIVATIVES OF NUCLEOSIDES AND THEIR ANALOGS, Bioorganiceskaa himia, 20(1), 1994, pp. 50-54
Alkylation of nucleosides and their analogues with p-toluenesulfonylox
ymethylphosphonic and its monoester allows to simplify the synthesis o
f the 5'-O-phosphonomethyl nucleoside derivatives.
