  • Electrochemical nickel-catalyzed Migita cross-coupling of 1-thiosugars with aryl, alkenyl and alkynyl bromides
    作者:Mingxiang Zhu、Mouad Alami、Samir Messaoudi
    DOI:10.1039/d0cc01126f
    日期:——
    Here we report a simple route towards the synthesis of thioglycosides, in which electrochemical cross-coupling is used to form a S-C glycosidic bond from protected and unprotected thiosugars with functionalized aryl bromides under base free conditions. The reaction manifold that we report here demonstrates the power of electrochemistry to access highly complex glycosides under mild conditions.
    在这里,我们报告了一种简单的合成糖苷的方法,其中电化学交叉偶联用于在无碱条件下由受保护和未受保护的糖与功能化的芳基化物形成SC糖苷键。我们在此报告的反应歧管证明了在温和条件下电化学作用可获取高度复杂的糖苷的能力。
  • Reversing Reactivity: Stereoselective Desulfurative 1,2-<i>trans</i>-<i>O</i>-Glycosylation of Anomeric Thiosugars with Carboxylic Acids under Copper or Cobalt Catalysis
    作者:Nedjwa Bennai、Amélie Chabrier、Maha I. Fatthalla、Christine Tran、Expédite Yen-Pon、Mohamed Belkadi、Mouâd Alami、Laurence Grimaud、Samir Messaoudi

    We have discovered a new mode of reactivity of 1-thiosugars in the presence of Cu(II) or Co(II) for a stereoselective O-glycosylation reaction. The process involves the use of a catalytic amount of Cu(acac)2 or Co(acac)2 and Ag2CO3 as an oxidant in α,α,α-trifluorotoluene. Moreover, this protocol turned out to have a broad scope, allowing the preparation of a wide range of complex substituted O-glycoside
    我们已经发现在立体选择性O-糖基化反应的Cu(II)或Co(II)存在下1-糖的反应性的新模式。该方法涉及使用催化量的Cu(acac)2或Co(acac)2和Ag 2 CO 3作为α,α,α-三氟甲苯中的氧化剂。而且,该方案证明具有广泛的范围,允许以良好的至优异的产率和排他的1,2-反式选择性制备多种复杂的取代的O-糖苷酯。还证明了通过这种方法对药物进行后期修饰。为了更深入地了解反应机理,进行了循环伏安法。
  • One-Pot Assembly of Unsymmetrical Biaryl Thioglycosides through Chemoselective Palladium-Catalyzed Three-Component Tandem Reaction
    作者:Sara Benmahdjoub、Nada Ibrahim、Belkacem Benmerad、Mouad Alami、Samir Messaoudi
    DOI:10.1021/acs.orglett.8b01624
    日期:2018.7.6
    A range of unsymmetrical biaryls bearing thiosugars could be synthesized in a one-pot multicomponent approach using one catalytic palladium system that permitted the C–S and C–C bonds to be formed sequentially. The reaction showed a high selectivity and was applied to a broad variety of substrates giving access to novel glycosylated biaryl structures in good yields.

    Buchwald–Hartwig–Migita cross-coupling of 1-thiosugars with 2-iodoglycals has been accomplished under mild and operationally simple reaction conditions through the use of Pd-G3 XantPhos palladacycle precatalyst. This new methodology has been successfully applied to a variety of α- or β-mono-, di-, and polythiosugar derivatives to synthesize efficiently a series of (1 → 2)-S-linked thiosaccharides and

    日期:2017.12.14
    A controllable method for the functionalization of XantPhos Pd‐G3 precatalyst with thiosugars and thiols has been established. Under mild and operationally simple reaction conditions through just mixing of precatalyst and thiosugars (α‐ or β‐mono‐, di‐ and poly‐thiosugar derivatives) in water at 25 °C for 20 min, a series of 1‐aminobiphenyl thioglycosides that are difficult to synthesize by classical
