An efficient method for the preparation of nucleoside 3'-H-phosphonothioate monoesters was developed. It consists of phosphonylation of suitably protected nucleosides with diphenyl H-phosphonate to produce nucleoside phenyl H-phosphonates, followed by their sulfhydrolysis with hydrogen sulfide.
Nucleoside H-Phosphonates are used directly in the synthesis of H-phosphonate linked deoxyoligonucleotides. A rapid and simplified procedure for the synthesis of deoxyoligonucleotides is described. Ribonucleoside H-phosphonate I. was introduced by Todd to prepare diribonucleotide 1 phosphate 4 (Sche
