Two routes are presented for the synthesis of 3',5'-bishomodeoxyribonucleosides, building blocks needed to synthesize oligodeoxynucleotide analogues where the OPO2O groups are replaced by CH2SCH2, CH2SOCH2, and CH2SO2CH2 units. Two of these have been coupled to create an uncharged analogue of a dinucleotide. As isosteric, achiral, and nonionic analogues of natural oligonucleotides stable to both enzymatic and chemical hydrolysis, such molecules have potential application as probes in the laboratory, in studies of the role of individual genes in biological function, and as ''antisense'' oligonucleotide analogues for the treatment of diseases.
