  含有新型 4'-C- 或 3'-C-(氨基烷基)-支化胸苷的寡核苷酸

  摘要：

  报道了四种新型 3'-C-支链和 4'-C-支链核苷的合成及其转化为相应的 3'-O-亚磷酰胺结构单元以用于自动寡核苷酸合成。4'-C-支化关键中间体11通过收敛策略合成并转化为其2'-O-甲基和2'-脱氧-2'-氟衍生物，从而制备出含有4'-的新型寡核苷酸类似物C-(氨基甲基)-2'-O-甲基单体X和4'-C-(氨基甲基)-2'-脱氧-2'-氟单体Y(方案2和3)。一般来说，与未修饰的参考相比，这些类似物对互补单链 DNA 和 RNA 的结合亲和力增加（表 1）。2'-O-甲基-RNA寡核苷酸中单体X或单体Y的存在对2'-O-甲基-RNA寡核苷酸对DNA和RNA的结合亲和力具有负面影响。从 3'-C-烯丙基衍生物 28 开始，合成了 3'-C-(3-氨基丙基)-保护的核苷和 3'-O-亚磷酰胺衍生物，从而产生了含有 3'-C-(3-氨基丙基）胸苷单体Z或相应的3'-C-（3-氨基丙基）-2'-O
