currently under investigation for that purpose. The synthesis of the required tetrafluorinated monosaccharides is achieved by a fluorinated building block approach. The enantioselective synthesis of tetrafluorinated hexose derivatives is described here, in both pyranose and furanose forms. In particular, the optimization of the enantioselective synthesis of the previously reported 2,3-dideoxy-2,2,3,3-
碳水化合物通常对蛋白质结合位点具有低亲和力,因此开发具有改进结合的碳水化合物模拟物是令人感兴趣的。单糖的四氟化是目前为此目的正在研究的策略之一。所需四氟化单糖的合成是通过氟化结构单元方法实现的。此处描述了吡喃糖和呋喃糖形式的四氟化己糖衍生物的对映选择性合成。特别是,优化了先前报道的 2,3-dideoxy-2,2,3,3-tetrafluoro- d - threo - hexopyranose 3 , 2,3-dideoxy-2,2,3,3-四氟-d-苏_-hexofuranose 4和 2,3-dideoxy-2,2,3,3-tetrafluoro- d - erythro -hexopyranose 5被描述为两种新型糖衍生物 3,4-dideoxy-3,3,4 的合成,4-四氟-d-苏-吡喃糖6和3,4-二脱氧-3,3,4,4-四氟-d-赤-吡喃糖7。所有合成的关键步骤是全氟烷基锂介导的
