  摘要：

  2'-Deoxyribo polyamide nucleic acids (2'-deoxyribo-PNAs) 3 are a new class of DNA analogs with a 2',3'-dideoxyribose-polyamide backbone structure. 2'-Deoxyribo-PNAs as well as chimeric oligonucleotide analogs with a mixed DNA / 2'-deoxyribo-PNA structure bind to single stranded complementary nucleic acids with similar affinities as natural DNA.

• Replacement of the phosphodiester linkage in oligonucleotides by heterocycles: synthesis of thymidine dinucleotide analogs with triazole-modified backbones
  作者：Peter von Matt、Thomas Lochmann、Karl-Heinz Altmann

  DOI：10.1016/s0960-894x(97)00269-2

  日期：1997.6

  Novel backbone-modified dinucleotide analogs of types V and VI have been synthesized, where the natural phosphodiester linkage of a T-T dinucleotide has been replaced by a triazole heterocycle. The key step of the synthesis is the regioselective, thermal cycloaddition of a 2-oxoalkylidene triphenylphosphorane with an azide derivative to generate the triazole ring.
