  • Triflic Imide‐Catalyzed Glycosylation of Disarmed Glycosyl <i>ortho</i> ‐Isopropenylphenylacetates and <i>ortho</i> ‐Isopropenylbenzyl Thioglycosides
    作者:Zhi Qiao、Peng Wang、Jingxuan Ni、Dongwei Li、Yao Sun、Tiantian Li、Ming Li

    日期:2022.1.17
    ortho-isopropenylphenylacetates and ortho-isopropenylbenzyl thioglycosides has been established. Mechanistically, the reaction involves the preferential protonation of the isopropenyl group, the generation of reactive glycosylating species by the cation-triggering intramolecular cyclization, and the ensuing glycosylation event.

  • Iodonium ion promoted reactions at the anomeric centre. II An efficient thioglycoside mediated approach toward the formation of 1,2-trans linked glycosides and glycosidic esters
    作者:G.H. Veeneman、S.H. van Leeuwen、J.H. van Boom

    日期:1990.1
    N-iodosuccinimide (NIS) in the presence of an organic acid was found to be effective for the activation of fully acylated thioglycosides leading to 1,2-trans linked esters. On the other hand, NIS together with a catalytic amount of trifluoromethanesulfonic acid proved to be very convenient for the rapid, high-yielding and stereoselective (1,2-trans) glycosidation of esterified thioglycosides with glycosyl
    发现在有机酸存在下,N-琥珀酰亚胺(NIS)可有效活化完全酰化的代糖苷,从而生成1,2-反式连接的。另一方面,NIS与催化量的三氟甲磺酸一起被证明对于用糖基受体对化的糖苷进行快速,高产和立体选择性(1,2-反式)糖苷化非常方便。
  • Stable Alkynyl Glycosyl Carbonates: Catalytic Anomeric Activation and Synthesis of a Tridecasaccharide Reminiscent of<i>Mycobacterium tuberculosis</i>Cell Wall Lipoarabinomannan

    日期:2016.6.27
    a challenging task despite the advent of modern glycosidation techniques. Herein, alkynyl glycosyl carbonates are shown to be stable glycosyl donors that can be activated catalytically by gold and silver salts at 25 °C in just 15 min to produce glycosides in excellent yields. Benzoyl glycosyl carbonate donors are solid compounds with a long shelf life. This operationally simple protocol was found to
    尽管现代糖苷化技术的出现,寡糖的合成仍然是一项艰巨的任务。本文中,炔基糖基碳酸显示为稳定的糖基供体,其可在25℃下仅15分钟内被盐催化活化,从而以优异的产率产生糖苷。甲酰基糖基碳酸供体是具有长保存期限的固体化合物。发现该操作简单的方案对于核苷,氨基酸以及叠氮基糖缀合物的合成是高效的。碳酸盐糖苷化方法的重复使用使得十三阿拉伯甘露聚糖能够以快速的方式高度收敛地合成。
  • Nucleofuge Generating Glycosidations by the Remote Activation of Hydroxybenzotriazolyl Glycosides

    by the extrusion of the oxocarbenium ion that was attacked by the glycosyl acceptor. Further, equilibration of the zwitterionic benzotriazolyl species makes the leaving group noncompetitive and generates the nucleofuge that has been reconverted to the glycosyl donor. The reaction is mild, high yielding, fast and suitable for donors containing both C2-ethers and C2-esters as well. The regenerative-donor
    羟基苯并三唑因其增加的反应性而通常用于肽化学中,以减少外消旋作用。在本文中,鉴定出非常稳定的羟基苯并三唑葡糖苷可以进行糖苷化。假设该反应通过Tf 2进行远程激活在HOBt的N3位点为O,接着是被糖基受体攻击的鎓离子的挤出。此外,两性离子并三唑基物质的平衡使离去基团失去竞争性,并产生已被重新转化为糖基供体的核沉子。该反应温和,高产率,快速并且适合于同时含有C2-醚和C2-的供体。再生供体糖苷化策略是有前途的,因为它使我们能够再生糖基供体以供进一步利用。通过成功合成HIV1-gp120复合物的支链五聚甘露聚糖核心,证明了该方法在寡糖合成中的实用性。
  • O,O-Dimethylthiophosphonosulfenyl bromide-silver triflate: a new powerful promoter system for the preactivation of thioglycosides
    作者:Peng Peng、Xin-Shan Ye
    DOI:10.1039/c0ob00380h
    日期:——
    O,O-Dimethylthiophosphonosulfenyl bromide (DMTPSB) in combination with silver triflate provides a powerful thiophilic promoter system. Both “armed” and “disarmed” thioglycoside glycosyl donors can be activated to form glycosidic linkages efficiently by the pre-activation protocol. The usefulness of this new promoter is illustrated by a successful iterative one-pot oligosaccharide assembly.
