  • 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。

    A simple and versatile glycosylation method with both armed and disarmed glycosyl ynenoates as donors is developed. Employing a gold(I) complex as catalyst with or without the assistance of TfOH, the scope of the present glycosylation protocol is very wide. The utility of the present ynenoate donors is demonstrated in the efficient synthesis of oligosaccharides via the latent-active strategy and the

  • <i>O</i>-Glycosylation Enabled by <i>N-</i>(Glycosyloxy)acetamides
    作者:Miao Liu、Bo-Han Li、De-Cai Xiong、Xin-Shan Ye
    DOI:10.1021/acs.joc.8b01003
    日期:2018.8.3
    A novel glycosylation protocol has been established by using N-(glycosyloxy)acetamides as glycosyl donors. The N-oxyacetamide leaving group in donors could be rapidly activated in the presence of Cu(OTf)2 or SnCl4 under microwave irradiation. This glycosylation process afforded the coupled products in high yields, and the reaction enjoyed a broad substrate scope, even for disarmed donors and hindered
    通过使用N-(糖基氧基)乙酰胺作为糖基供体已经建立了新的糖基化方案。在微波辐射下,存在Cu(OTf)2或SnCl 4的情况下,供体中的N-氧乙酰胺离去基团可以快速活化。该糖基化过程以高收率提供了偶联产物,并且该反应享有广泛的底物范围,即使对于缴械的供体和受阻的受体也是如此。供体的容易获得,N-(糖基氧基)乙酰胺的高稳定性以及小的离去基团使该方法非常实用。

    FeCl3 can also modulate the 1,2-trans selectivity of the reaction of 2-O-alkylated gluco- and galacto-pyranosyl trichloroacetimidates with phenolic compounds leading to the generation of the corresponding β-O-aryl glycosides in excellent yield and selectivity. Apart from these the present methodology has been successfully utilized for double glycosylation and orthogonal glycosylation reactions along
    人们已经集中研究了一种新的糖基化方法,该方法可从10摩尔%的FeCl 3介导的相应的三氯乙酰亚氨酸酯供体有效立体选择性合成β-葡萄糖和半乳糖苷。FeCl 3也已应用于许多基于葡萄糖,半乳糖,甘露糖和鼠李糖的三氯乙酰亚氨酸酯供体,这些供体在C-2位置掺入了各种保护基,从而制备了多种具有优异的1,2-反式选择性的二糖和三糖。FeCl 3还可调节2- O反应的1,2-反式选择性-烷基化的葡糖基和半乳糖基-吡喃糖基三氯乙酰亚胺酸酯与酚类化合物的结合,可导致以优异的产率和选择性生成相应的β- O-芳基糖苷。除此之外,本方法已成功地用于双糖基化和正交糖基化反应,以及在三锅合成的一锅三组分正交糖基化反应中的应用。
