  • Nickel-catalyzed reductive coupling of glucosyl halides with aryl/vinyl halides enabling β-selective preparation of C-aryl/vinyl glucosides
    作者:Jiandong Liu、Chuanhu Lei、Hegui Gong
    DOI:10.1007/s11426-019-9501-4
    日期:2019.11
    This work describes stereoselective preparation of β-C-aryl/vinyl glucosides via mild Ni-catalyzed reductive arylation and vinylation of C1-glucosyl halides with aryl and vinyl halides. A broad range of aryl halides and vinyl halides were employed to yield C-aryl/vinyl glucosides in 42%–93% yields. Good to excellent β-selectivities were obtained for C-glucosides by using tridentate ligand.
    这项工作描述了通过温和的Ni催化的还原性芳基化和C 1-葡萄糖基卤化物与芳基和乙烯基卤化物的乙烯基化,立体选择性地制备β- C-芳基/乙烯基葡糖苷。广泛使用的芳基卤化物和乙烯基卤化物可产生C-芳基/乙烯基葡糖苷,产率为42%–93%。通过使用三齿配体,对C-葡糖苷获得了良好至优异的β-选择性。

    We have developed a novel diastereoselective iron-catalyzed cross-coupling reaction of various glycosyl halides with aryl metal reagents for the efficient synthesis of aryl C-glycosides, which are of significant pharmaceutical interest due to their biological activities and resistance toward metabolic degradation. A variety of aryl, heteroaryl, and vinyl metal reagents can be cross-coupled with glycosyl
    我们开发了一种新型的非对映选择性催化的各种糖基卤化物与芳基属试剂的交叉偶联反应,用于有效合成芳基 C-糖苷,由于它们的生物活性和对代谢降解的抵抗力,它们具有重要的药学价值。在由 (II) 和庞大的双膦配体 TMS-SciOPP 组成的明确定义的络合物的存在下,各种芳基、杂芳基和乙烯基属试剂可以与糖基卤化物以高产率交叉偶联。该反应的化学选择性允许使用合成通用的乙酰保护糖基供体,并在芳基部分结合各种官能团,产生多种芳基 C-糖苷,包括 Canagliflozin、一种-葡萄糖协同转运蛋白 2 (SGLT2) 抑制剂和一种流行的糖尿病药物。交叉偶联反应通过糖基自由基中间体的生成和立体选择性捕获进行,代表了基于催化的高度立体选择性碳-碳键形成的罕见例子。使用 3,4,6-tri-O-acetyl-2-O-allyl-α-d-glupyranosyl bromide (8) 和 6-bromo-1-hexene
  • Diastereoselective Ni-Catalyzed Negishi Cross-Coupling Approach to Saturated, Fully Oxygenated <i>C</i>-Alkyl and <i>C</i>-Aryl Glycosides
    作者:Hegui Gong、Michel R. Gagné
    DOI:10.1021/ja8041564
    日期:2008.9.10
    A Ni-catalyzed Negishi cross-coupling approach to C-glycosides is described with an emphasis on C-aryl glycosides. The combination of NiCl2/PyBox in N,N'-dimethylimidazolidinone (DMI) enabled the synthesis of C-alkyl glycosides under mild reaction conditions. Moderate yields and beta-selectivities were obtained for C-glucosides, and good yields and high alpha-selectivities were the norm for C-mannosides
    介绍了一种 Ni 催化的 Negishi 交叉偶联方法来处理 C-糖苷,重点是 C-芳基糖苷。NiCl2/PyBox 在 N,N'-二甲基咪唑烷酮 (DMI) 中的组合能够在温和的反应条件下合成 C-烷基糖苷。C-葡萄糖苷获得了中等的产量和β-选择性,而良好的产量和高α-选择性是C-甘露糖苷的标准。对于 C-芳基糖苷,在 N,N-二甲基甲酰胺 (DMF) 中使用 Ni(COD)2/(t)Bu-Terpy 的反应通常具有高产率,并提供具有高 β-选择性(1:>10 α: beta) 和 C-甘露糖苷具有中等 alpha 选择性 (3:1 alpha:beta);α-C-芳基糖苷可以通过 Ni(COD)2/PyBox 在 DMF (>20:1 alpha:beta) 中的组合获得。集体研究表明,C-糖苷的立体化学控制取决于底物和催化剂的组合。Negishi 协议显示出出色的官能团耐受性,正如其在天然产物沙甲素
