  • Electron-deficient pyridinium salts/thiourea cooperative catalyzed <i>O</i>-glycosylation via activation of <i>O</i>-glycosyl trichloroacetimidate donors
    作者:Mukta Shaw、Yogesh Kumar、Rima Thakur、Amit Kumar
    DOI:10.3762/bjoc.13.236
    日期:——
    The glycosylation of O-glycosyl trichloroacetimidate donors using a synergistic catalytic system of electron-deficient pyridinium salts/aryl thiourea derivatives at room temperature is demonstrated. The acidity of the adduct formed by the 1,2-addition of alcohol to the electron-deficient pyridinium salt is increased in the presence of an aryl thiourea derivative as an hydrogen-bonding cocatalyst. This
    证明了在室温下使用缺电子的吡啶鎓盐/芳基硫脲衍生物的协同催化系统对O-糖基三氯乙酰基亚氨酸酯供体的糖基化作用。在芳基硫脲衍生物作为氢键合助催化剂的存在下,由醇向缺电子的吡啶鎓盐的1,2-加成形成的加合物的酸度增加。这种转化在温和的反应条件下进行,反应条件与各种O-糖基三氯乙酰亚氨酸酯供体和糖基受体结合,以中等到良好的产率提供了可预测的选择性的相应O-糖苷。另外,通过使用部分保护的受体,优化的方法也用于区域选择性的O-糖基化。
  • Stereoselective Glycosylation Reactions

    公开号:US20140303359A1
    公开(公告)日:2014-10-09
    Disclosed is a method for selective synthesis of 1,2-cis-α-linked glycosides which does not require the use of the specialized protecting group patterns normally employed to control diastereoselectivity. Thioglycoside acceptors can be used, permitting iterative oligosaccharide synthesis. The approach eliminates the need for lengthy syntheses of monosaccharides possessing highly specialized and unconventional protecting group patterns.
    揭示了一种选择性合成1,2-顺式α-连接的糖苷的方法,该方法不需要通常用于控制对映选择性的专门保护基团模式。可以使用硫代糖苷受体,从而允许进行寡糖合成。该方法消除了需要合成具有高度专门化和非常规保护基团模式的单糖的冗长合成过程。
  • An efficient construction of 1,2-trans-β-glycosidic linkages capitalizing on glycopyranosyl N,N,N′,N′-tetramethylphosphroamidates as shelf-stable glycosyl donors

    日期:1992.6
    stereocontrolled 1,2-trans-β-glycosidation reaction with or without neighbouring group participation has been developed by using benzyl- or benzoyl-protected glycopyranosyl N,N,N',N'-tetramethylphosphoroamidates as shelf-stable glycosyl donors in the presence of trimethylsilyl trifluoromethanesulfonate or boron trifluoride etherate. Several notable features of the present method not observed with the diphenyl

    Generally applicable and stereoselective formation of 1,2-cis-glycopyranosidic linkage remains a long sought after yet unmet goal in carbohydrate chemistry. This work advances a strategy to this challenge via stereoinversion at the anomeric position of 1,2-trans glycosyl ester donors. This SN2 glycosylation is enabled under gold catalysis by an oxazole-based directing group optimally tethered to a
    1,2-顺式-吡喃糖苷键的普遍适用和立体选择性形成仍然是碳水化合物化学中长期追求但尚未实现的目标。这项工作通过在 1,2-反式糖基酯供体的异头位置上的立体倒置推进了应对这一挑战的策略。这种 S N 2 糖基化是在金催化下通过以恶唑为基础的导向基团实现的,该导向基团最佳地束缚在离去基团上,并在温和的催化条件下以大多数优异的产率和良好的选择性实现。该策略也适用于寡糖的合成。

    作者:Jhe-Cyuan Hu、Ai-Fen Wendy Feng、Bo-Yao Chang、Chun-Hung Lin、Kwok-Kong Tony Mong
    DOI:10.1039/c7ob00839b
    日期:——
    strategy for a wide range of glycosyl donors and acceptors has been developed, which is based on an in situ adduct transformation protocol. Based on this strategy, both NFM-derived and iodide covalent adducts can be accessed for glycosylation. Using low temperature NMR spectroscopy, the aforementioned glycosyl adducts were detected.
