Efficient synthesis of the 5′-deoxy-5′-methylphosphonate linked thymidine dimer 11 [p(ch2Tp(ch2T] was developed via the 5′-deoxy-5′-C-(phosphonomethyl)-3′-silylated thymidine derivative 4 as a key intermediate. Conformational analysis of the sugar parts of the dimer showed that the deoxyribose residues exist in solution mainly in the S-type conformations but with a predominant contribution of antiperiplanar

Thymidine deoxyoligonucleotides having a 5′-deoxy-5′-methylidynephosphonate internucleotide linkage were synthesized. Relative to natural DNA, these oligomers were nuclease resistant and formed duplexes with reduced stability.
