  General Synthesis and Binding Affinity of Position-Selective Phosphonodiester- and Phosphotriester-Incorporated Oligodeoxyribonucleotides

  摘要：

  Synthesis of phosphonodiester- and phosphotriester-modified oligodeoxyribonucleotides has been accomplished via the phosphoramidite approach with allylic protection. The modification can be made at the selected position(s) of the oligomers. The efficiency of this method has been demonstrated by the synthesis of base-labile modified oligo(deoxyribonucleotide)s such as the methyl phosphates and phenylphosphonates. Melting temperatures of the duplexes containing these artificial strands indicate that the backbone-alternation, which is made at a single site, does not have a negative influence on the binding affinity to the complementary DNA.
