Abstract/OtherAbstract:
The synthesis of monomers (S)-1, (R)-1 and 2 derived from (5'S)-, (5'R)-2'-deoxythymidine-5'-C-phosphonic acids and 2',5'-dideoxythymidine-5'-C-phosphonic acids was elaborated. The protection of the 5'-hydroxyl by the methoxycarbonyl group was a key step of the synthesis. Prepared monomers were used for the solid-phase assembly of several types oligothymidylate 15-mers (S)-3, (S)-4, (S)-5, (R)-4 and (R)-5 containing the chiral 3'-O-P-CH(OH)-5'' internucleotide linkage. Their hybridization properties with dA15 and rA15 were studied as well as their resistance against nuclease cleavage.
