  • Stereoselective Glycosylation Reactions
    申请人:Trustees of Tufts College
    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 Air- and Water-Stable Iodonium Salt Promoter for Facile Thioglycoside Activation
    作者:An-Hsiang Adam Chu、Andrei Minciunescu、Vittorio Montanari、Krishna Kumar、Clay S. Bennett

    日期:2014.3.21
    iodonium salt phenyl(trifluoroethyl)iodonium triflimide is shown to activate thioglycosides for glycosylation at room temperature. Both armed and disarmed thioglycosides rapidly undergo glycosylation in 68–97% yield. The reaction conditions are mild and do not require strict exclusion of air and moisture. The operational simplicity of the method should allow experimentalists with a limited synthetic background
    空气和水稳定的碘鎓盐苯基(三氟乙基)碘鎓三氟甲磺酰亚胺在室温下可激活硫代糖苷以进行糖基化。武装和解除武装的硫糖苷都以 68-97% 的产率迅速进行糖基化。反应条件温和,不需要严格排除空气和水分。该方法的操作简单性应该允许具有有限合成背景的实验者构建糖苷键。
  • <i>O</i>-Glycosylation Enabled by <i>N-</i>(Glycosyloxy)acetamides
    作者:Miao Liu、Bo-Han Li、De-Cai Xiong、Xin-Shan Ye

    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。
  • Palladium(<scp>ii</scp>)-assisted activation of thioglycosides
    作者:Samira Escopy、Yashapal Singh、Alexei V. Demchenko
    DOI:10.1039/d1ob00004g
    日期:——
    Described herein is the first example of glycosidation of thioglycosides in the presence of palladium(II) bromide. While the activation with PdBr2 alone was proven feasible, higher yields and cleaner reactions were achieved when these glycosylations were performed in the presence of propargyl bromide as an additive. Preliminary mechanistic studies suggest that propargyl bromide assists the reaction
    本文描述的是在溴化钯( II )存在下硫代糖苷的糖苷化的第一个实例。虽然单独使用 PdBr 2进行活化已被证明是可行的,但当这些糖基化在炔丙基溴作为添加剂存在的情况下进行时,可以实现更高的产率和更清洁的反应。初步机理研究表明,炔丙基溴通过产生电离络合物来促进反应,从而加速离去基团的离开。研究了与不同糖基受体反应的各种硫代糖苷供体,以确定这种新反应的初始范围。还探索了硫代糖苷相对于其他离去基团的选择性和化学选择性激活。
  • Cooperative Catalysis in Glycosidation Reactions with<i>O</i>-Glycosyl Trichloroacetimidates as Glycosyl Donors

    Thiourea mediates cooperative glycosidation through hydrogen bonding. N,N′‐Diarylthiourea as cocatalyst enforces an SN2‐type acid‐catalyzed glycosidation even at room temperature (see scheme; Bn=benzyl). From O‐(α‐glycosyl) trichloroacetimidates as glycosyl donors and various acceptors, β‐glycosides are preferentially or exclusively obtained.
    硫脲通过氢键介导协同糖基化。N,N'-二芳基硫脲作为助催化剂即使在室温下也可增强S N 2型酸催化的糖苷化作用(见方案; Bn =苄基)。从O-(α-糖基)三氯乙酰亚氨酸盐作为糖基供体和各种受体,可以优先或仅从中获得β-糖苷。
