(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.

[formula: see text] The controlled and selective synthesis of oligonucleotides on the solid phase is possible under mild aqueous conditions using the enzyme T4 RNA ligase, the resins being tentagel or kieselguhr/polydimethylacrylamide.
