  • β‐Selective <i>C</i> ‐Glycosylation and its Application in the Synthesis of Scleropentaside A
    作者:G. Jacob Boehlich、Nina Schützenmeister
    DOI:10.1002/anie.201900995
    日期:2019.4
    C‐Glycosides are carbohydrates that bear a C−C bond to an aglycon at the anomeric center. Due to their high stability towards chemical and enzymatic hydrolysis, these compounds are widely used as carbohydrate mimics in drug development. Herein, we report a general and exclusively β‐selective method for the synthesis of a naturally abundant acyl‐C‐glycosidic structural motif first found in the scleropentaside

  • β-Selective One-Pot Synthesis of Acyl-C-Glycosides via Corey–Seebach Umpolung Reaction
    作者:G. Jacob Boehlich、Nina Schützenmeister

    日期:2019.10

    C-Glycosides are commonly used as carbohydrate mimics in drug development due to their stability against enzymatic and chemical hydrolysis. In this Synpacts article we elaborate on our fast and efficient β-selective approach towards protected and unprotected acyl glycosides. Application of a Corey–Seebach umpolung reaction enables the exclusive formation of the β-anomer of aromatic acyl-C-glycosides in good to excellent yields.

    C-糖苷在药物开发中常被用作碳水化合物的模拟物,因为它们对酶促和化学水解具有稳定性。在这篇Synpacts文章中,我们详细介绍了我们快速高效的β-选择性方法,用于合成受保护和未受保护的酰基糖苷。应用Corey–Seebach反转反应能够专一性地形成芳香酰基-C-糖苷的β-异构体,并且产率良好到优秀。 1 引言 2 苄基化糖基供体的C-糖基化 3 硅基化糖基供体的C-糖基化 4 结论
  • Versatile Glycosyl Sulfonates in β‐Selective C‐Glycosylation
    作者:Jesse Ling、Clay S. Bennett
    DOI:10.1002/anie.201914221
    日期:2020.3.9
    AbstractC‐Glycosides are both a common motif in many bioactive natural products and important glycoside mimetics. We demonstrate that activating a hemiacetal with a sulfonyl chloride, followed by treating the resultant glycosyl sulfonate with an enolate results in the stereospecific construction of β‐linked C‐glycosides. This reaction tolerates a range of acceptors and donors, including disaccharides. The resulting products can be readily derivatized into C‐glycoside analogues of β‐glycoconjugates, including C‐disaccharide mimetics.
