(Chemical Equation Presented) The phosphoramidite 11 was prepared in three steps from methyl 2-mercaptoacetate and demonstrated efficiency in the synthesis of conventional 5′-/3′-phosphate/thiophosphate monoester derivatives of 2′-deoxyribonucleosides and DNA oligonucleotides. Moreover, the use of 11 has enabled the preparation of the dinucleoside phosphorothioate analogue 26 in high yields (>95%) with minimal cleavage (2%) of the thermolytic thiophosphate protecting group.

We have developed a convenient method for achieving the oxidation of nucleoside H-phosphonic acid monoesters and diesters with bis(trimethylsilyl) peroxide and N,O-bis(trimethylsilyl)acetamide in the presence of trimethylsilyl triflate as a catalyst.
