  3′-Deoxy-3′-C-trifluoromethyl Nucleosides: Synthesis and Antiviral Evaluation

  摘要：

  2',3'-Dideoxy-3'-C-trifluoromethylthymidine 9a and -uridine 9b and 3'-C-trifluoromethyl-d(4)T 11 were prepared in a few steps from 3'-deoxy-3'-C-trifluoromethyl-D-ribose, which synthesis was recently reported. The biological assessment of these nucleoside analogues did not reveal interesting antiviral properties against HIV-1, HSV-1, CMV, Vaccine, and Cox B4.

  The present invention relates to nucleoside compositions comprising novel nucleobases and oligomeric compounds comprising at least one such nucleoside. These oligomeric compounds typically have enhanced binding affinity properties compared to oligomeric compounds without the modification. The oligomeric compounds are useful, for example, for investigative and therapeutic purposes.

  本发明涉及包含新型核碱基的核苷酸组合物以及包含至少一种此类核苷酸的寡聚合物化合物。这些寡聚合物化合物通常具有比没有这种修饰的寡聚合物化合物更强的结合亲和性能。这些寡聚合物化合物可用于调查和治疗等用途。

  An acyclonucleoside synthesis was investigated on the regioselective introduction of an acyclochain. We found that iodotrimethylsilane catalyzed the reaction of acyclochain introduction as well as its migration from S-2 to N-1 of 2-thiothymine and from N-7 to N-9 position of guanine. By taking the findings into account, several acyclonucleosides were synthesized in a simple one-pot procedure.

  The reaction of 3,5-O-(1,1,3,3-tetraisopropyldisiloxane-1,3-diyl)-2-O-methylribofuranos-1-yl trichloroacetimidate as the ribosyl donor with bis(trimethylsilyl)thymine was studied in detail. As the result, it was concluded that the main product is an alpha-glycoside derivative unlike the previous report. In connection with this glycosylation, several chemical properties of the byproduct obtained by the Chapman rearrangement are described.
