  • Ready Transformation of Partially Unprotected Thioglycosides into Glycosyl Fluorides Mediated by NIS/HF-Pyridine or Et<sub>3</sub>N·3HF
    作者:J. Cristóbal López、Paloma Bernal-Albert、Clara Uriel、Ana M. Gómez

    日期:2008.10
    The transformation of partially unprotected phenyl 1-thioglycosides into glycosyl fluorides can be conveniently carried out by treatment with NIS in the presence of HF–pyridine. Other sources of halonium ions such as NBS, IDCP, have also been employed. The combination NIS/Et3N·3HF, where triethylamine–tris(hydrogen fluoride) (Et3N·3HF) replaces HF–pyridine, can also effect this transformation when
    在 HF-吡啶存在下用 NIS 处理可以方便地将部分未保护的苯基 1-硫代糖苷转化为糖基氟。还使用了其他卤离子源,例如 NBS、IDCP。当存在对酸敏感的取代基时,NIS/Et3N·3HF 组合(其中三乙胺-三(氟化氢)(Et3N·3HF)代替 HF-吡啶)也可以影响这种转化。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
  • Endocyclic Cleavage in Glycosides with 2,3-<i>trans</i> Cyclic Protecting Groups

    is proposed as a reaction mechanism for the anomerization from the β (1,2-trans) to the α (1,2-cis) configuration observed in glycosides carrying 2,3-trans cyclic protecting groups. This reaction occurs in the presence of a weak Lewis or Brønsted acid, while endocyclic cleavage (endocleavage) in typical glycosides was observed only when mediated by protic media or strong Lewis acids. To rationalize
    提出了内环途径作为在携带 2,3-反式环状保护基团的糖苷中观察到的从 β(1,2-反式)到 α(1,2-顺式)构型异构化的反应机制。该反应在弱路易斯酸或布朗斯台德酸存在下发生,而典型糖苷中的环内裂解(内裂解)仅在质子介质或强路易斯酸介导时观察到。为了使这类化合物的行为合理化,使用量子力学 (QM) 计算和实验研究研究了内切的反应机制和促进因素。我们研究了携带 2,3-反式环状保护基团的硫糖苷的异构化反应,使用三氟化硼醚合物 (BF(3)·OEt(2)) 作为路易斯酸。估计的理论反应性,基于一个简单的模型来预测由稠环引起的应变的过渡态 (TS) 能量,非常接近通过内 CO 键断裂后沿 C1-C2 键旋转的 TS 搜索计算的 TS 能量。在预测的 TS 能量和实验反应性等级之间发现了极好的一致性。这一系列的计算和实验强烈支持内环而不是外环机制的优势。此外,这些研究表明内部应变是增强内切反应的主
  • Stereocontrolled Formation of β-Glucosides and Related Linkages in the Absence of Neighboring Group Participation:  Influence of a <i>trans</i>-Fused 2,3-<i>O</i>-Carbonate Group
    作者:David Crich、Prasanna Jayalath
    DOI:10.1021/jo0508999
    日期:2005.9.1
    [GRAPHICS]Phenyl 4,6-di-O-benzyl-2,3-O-carbonyl-beta-D-glucothiopyranoside and the regiosiomeric phenyl 2,6-di-O-benzyl-3,4-O-carbonyl-beta-D-glucothiopyranoside were prepared and studied as glucosyl donors at -60 degrees C in dichloromethane with preactivation by 1-benzenesulfinyl piperidine before addition of the acceptor alcohol. The 2,3-O-carbonate protected donor showed moderate to excellent beta-selectivity under these conditions depending on the acceptor employed, thereby providing a means for 1,2-trans-equatorial glycosidic bonds without recourse to neighboring group participation and its associated problem of ortho ester formation. In contrast, the 3,4-O-carbonate protected donor showed moderate to no beta-selectivity under the conditions employed. The results obtained in this study with carbonate protected glucopyranosyl donors are contrasted with those obtained previously in the manno- and rhamnopyranosyl series when the 2,3-O-carbonate protected is (x-selective and the 3,4-O-carbonate is beta-selective.
  • Synthesis of 6-Sulfonatomethyl Thioglycosides by Nucleophilic Substitution: Methods to Prevent 1→6 Anomeric Group Migration of Thioglycoside 6-<i>O</i>-Triflates

    position of thioglycosides by nucleophilic displacement of the corresponding 6-O-triflate is described. The 16 migration of the anomeric group, which inevitably occurs through a bicyclic sulfonium ion intermediate, from conformationally flexible β-thioglycosides was prevented by using an α-thioglycoside or conformationally locked β-thioglycoside as the starting material. The thioglycoside 6-sulfonic
    描述了通过相应 6-O-三氟甲磺酸酯的亲核置换将磺基甲基部分引入硫糖苷的主要位置。通过使用 α-硫糖苷或构象锁定的 β-硫糖苷作为起始材料,可以防止异头基团从构象灵活的 β-硫糖苷中不可避免地通过双环锍离子中间体发生 1→6 迁移。硫糖苷 6-磺酸在合成含肝素三糖的糖醛酸过程中表现出优异的 α 选择性。
