Building blocks for oligonucleotide analogs with dimethylene-sulfide, -sulfoxide, and -sulfone groups replacing phosphodiester linkages

Article abstract of DOI:10.1016/S0040-4039(00)94548-9

Routes are presented for the synthesis of 3',5'-bishomo-deoxyribonucleosides, building blocks needed to synthesize oligonucleotide analogs where the -O-PO₂-O- groups are replaced by -CH₂-SO₂-CH₂-,-CH₂
