  • Synthesis of spirostanol saponins via gold(I)‐catalyzed glycosylation in the presence of Ga(OTf) <sub>3</sub> , In(OTf) <sub>3</sub> , or HOTf
    作者:Teddy Stephen Ehianeta、Dacheng Shen、Peng Xu、Biao Yu
    DOI:10.1002/cjoc.201900126
    日期:2019.8
    gold(I)‐catalyzed glycosylation has been reported in the synthesis of a panel of the representative natural spirostanol saponins, namely polyphyllin D (1), polyphyllin V (2), dioscin (3), formosanin C (4), and a derivative of polyphyllin D bearing a terminal azide group (5). This approach highlights the engagement of low loadings of Ph3AuPOTf (≤ 0.5 mol%) in the presence of Ga(OTf)3, In(OTf)3, or HOTf

  • Access to Diosgenyl Glycoconjugates via Gold(I)-Catalyzed Etherification of Diosgen-3-yl <i>ortho</i>-Hexynylbenzoate
    作者:Li Zhang、Linfeng Li、Shujin Bai、Xin Zhou、Peng Wang、Ming Li
    DOI:10.1021/acs.orglett.6b02963
    日期:2016.12.2
    An efficient protocol for the synthesis of diverse diosgen-3-yl glycoconjugates, a class of novel synthetic analogs of natural saponins of biological significance, has been developed. The method relies on gold(I)-catalyzed etherification of diosgen-3-yl ortho-hexynylbenzoate with stoichiometric sugar alcohols to afford the corresponding glycoconjugates in 38%–99% yields. The reaction involves the preferential
    已经开发出一种有效的方案,用于合成各种具有生物意义的天然皂苷的新型薯di皂苷-3-基糖缀合物。该方法依赖于金(I)催化的化学计量的糖醇对异三-3-基邻己基苯甲酸酯进行醚化的金(I)催化,以38%–99%的收率提供相应的糖结合物。该反应涉及羟基优先攻击均烯丙基碳阳离子中间体的C3位置,并显示出较宽的底物范围和良好的官能团耐受性。
  • 4-(tert-Butyldiphenylsilyloxy)-2,2-dimethylbutanoyl: An Easily Removable Pivaloyl-Type Protecting Group with High Orthogonality
    作者:Ming Li、Qishuai Li、Yong Su、Zhi Qiao、Jianjun Wang、Peng Wang、Sumei Ren、Ni Song

    日期:2022.6
    Protecting groups play multiple and vital roles during the synthesis of carbohydrates and other natural products. We herein report the installation and orthogonal cleavage, under mild conditions, of a 4-(tert-butyldiphenylsilyloxy)-2,2-dimethylbutanoyl (BDMB) group as a sterically hindered pivaloyl-type hydroxy protecting group. The compatibility of this substituent with the removal of other protecting
    保护基团在碳水化合物和其他天然产物的合成过程中发挥着多重和重要的作用。我们在此报告了在温和条件下安装和正交裂解 4-(叔丁基二苯基甲硅烷氧基)-2,2-二甲基丁酰基 (BDMB) 基团作为空间受阻的新戊酰基型羟基保护基团。还研究了该取代基与去除其他保护基团的相容性。由于其有利的特性,预计 BDMB 可作为一种有价值的羟基掩蔽剂。
