  • Nucleosides and Nucleotides. 108. Synthesis and Optical Properties of Syn-Fixed Carbon-Bridged Pyrimidine Cyclonuclesides.
    作者:Yuichi YOSHIMURA、Brian A. OTTER、Tohru UEDA、Akira MATSUDA
    DOI:10.1248/cpb.40.1761
    日期:——
    6, 1'-Propanouridine (10), a carbon-bridged cyclouridine fixed in the syn-conformation, was synthesized from D-fructose. Two additional carbon-units were introduced at the 1'-position of 1'-hydroxymethyl-O2, 2'-anhydrouridine 13 and inversion of the 2' hydroxyl group was achieved by sequential oxidation-reduction reactions. Finally, the spiro-carbon bridge was constructed by radical cyclization of the 1'-iodopropyl derivative of 5-chlorouridine. Dehydrochlorination followed by deprotection gave the desired 10. The circular dichroism (CD) spectrum of 10 showed a negative Cotton effect ([θ]=-6100) at the main absorption region, whereas 5'-O-tert-butyldimethylsilyl-2', 3'-O-isopropylidene-6, 1'-propanouridine (30) showed almost no Cotton band at the same absorption region. These results suggest that the critical region in which the CD Cotton effect changes from negative to positive is present in the syn region where 10 is located. Correlation of the magnitude and the direction of the sign of the CD Cotton effect and the torsion angle (χ) is also discussed.
    6, 1'-丙尿苷 (10) 是一种以顺式构象固定的碳桥环尿苷,由 D-果糖合成。在1'-羟甲基-O2、2'-脱尿苷13的1'位引入两个额外的碳单元,并通过连续的氧化还原反应实现2'羟基的反转。最后,通过5-尿苷的1'-丙基衍生物的自由基环化构建了螺碳桥。脱氯化氢,然后脱保护得到所需的10。10的圆二色性(CD)光谱在主吸收区域显示负Cotton效应([θ]=-6100),而5'-O-叔丁基二甲基甲硅烷基-2', 3'-O-异亚丙基-6, 1'-丙尿苷 (30) 在同一吸收区域几乎没有显示出 Cotton 谱带。这些结果表明,CD Cotton效应从负值变为正值的关键区域存在于10所在的syn区域中。还讨论了 CD Cotton 效应的符号大小和方向与扭转角 (χ) 的相关性。
  • A Convenient Synthesis of D-Psicofuranosyl Nucleosides1
    作者:Mallela Sarmastate、Sreenivasulu Megati、Robert Klein、Brian Otter

    Abstract As part of our studies on the synthesis of conformationally restricted nucleosides of types 1 and 2, where X = CH2, O or S, we required access to differentially substituted D-psicofuranosyl nucleosides such as 3. As shown in the table, we have developed a convenient approach to such compounds that depends on the direct condensation of the 1,2:3,4-di-O-isopropylidene-β-D-psicofuranose derivative
    摘要作为我们合成1和2型构象受限核苷(其中X = CH2,O或S)的研究的一部分,我们需要获得3等差异取代的D-psicofuranosyl核苷。如表所示,我们有1,2,3,4-二-O-异亚丙基-β-D-四氢呋喃糖衍生物4与合适的甲硅烷基化嘌呤嘧啶碱直接缩合,开发了一种简便的方法来处理这类化合物2。 3的β端基异构体以1:1的比例形成,β端基异构体的收率一般可与使用psicofuranosyl-halide2、2-苯甲酸酯4或2-硝基衍生物5的早期缩合方法相媲美。但是,本方法的优点是更容易获得起始糖4。
