  • Versatile acetylation of carbohydrate substrates with bench-top sulfonic acids and application to one-pot syntheses of peracetylated thioglycosides
    作者:Chin-Sheng Chao、Min-Chun Chen、Shih-Che Lin、Kwok-Kong T. Mong
    DOI:10.1016/j.carres.2008.01.014
    日期:2008.4
    sulfonic acids, p-toluenesulfonic acid, and sulfuric acid are versatile and efficient catalysts for the peracetylation of a broad spectrum of carbohydrate substrates in good yield and in a practical time frame. Three appealing features in sulfonic acid-catalyzed acetylation of free sugars were explored including (1) suppression of furanosyl acetate formation for D-galactose and L-fucose; (2) high yielding
    廉价且容易获得的磺酸对甲苯磺酸硫酸是通用且有效的催化剂,用于以良好的收率和在实际的时间范围内对多种碳水化合物底物进行过乙酰化。研究了磺酸催化游离糖乙酰化的三个吸引人的特征,包括:(1)抑制D-半乳糖L-岩藻糖呋喃糖基乙酸酯的形成;(2)在适当条件下高产率的唾液酸化学选择性乙酰化;(3)具有不同基保护功能的基糖过乙酰化。还描述了简单的一锅两步乙酰化-代糖苷化方法,用于快速合成对甲苯基过-O-乙酰基代糖苷。
  • The Fusion Synthesis of Aryl 1-Thioglycosides
    作者:Toshisada Shimadate、Sachiyo Chiba、Kazuko Inouye、Teruhiko Iino、Yoshiyuki Hosoyama
    DOI:10.1246/bcsj.55.3552
    日期:1982.11
    A simple method for the preparation of aryl 1-thioglycosides is described. The reaction of D-glucose pentaacetate or 2-acetamido-2-deoxy-D-glucose tetraacetate with arenethiols in the presence of zinc chloride under fusion conditions formed their 1-thioglycosides in good yields. Some Lewis acids in addition to zinc chloride were studied as catalysts in the reaction.
    描述了一种制备芳基 1-糖苷的简单方法。D-葡萄糖乙酸酯或2-乙酰基-2-脱氧-D-葡萄糖四乙酸酯与芳烃醇在氯化锌存在下在融合条件下反应以良好的产率形成它们的1-代糖苷。除了氯化锌外,还研究了一些路易斯酸作为反应中的催化剂。
  • Solvent-free synthesis of thioglycosides by ball milling

    Thioglycosides have been prepared in excellent yields by three different routes from a range of readily available glycosyl halides under solvent-free conditions employing a planetary ball mill.

    The solvent free per-O-acetylation of various reducing and non-reducing sugars has been carried out using stoichiometric amounts of acetic anhydride and copper(ii) perchlorate hexahydrate as the catalyst.

    各种还原糖和非还原糖的无溶剂O-乙酰化反应已经使用等物质量的乙酸酐和六氯酸铜(ii)作为催化剂进行。
  • Reinvestigation of <i>N</i>,<i>N</i>-Diacetylimido-Protected 2-Aminothioglycosides in <i>O</i>-Glycosylation: Intermolecular Hydrogen Bonds Contributing to 1,2-Orthoamide Formation
    作者:Liming Shao、Zhenni Huo、Na Lei、Min Yang、Zehuan He、Yongliang Zhang、Qinlong Wei、Changsheng Chen、Mei Xiao、Fei Wang、Guofeng Gu、Feng Cai
    DOI:10.1021/acs.joc.1c01009
    日期:2021.10.1
    N,N-Diacetylimido protection of 2-aminoglycosides is an elegant strategy but has had limited applications due to unexpected side reactions in glycosylation. We found that high acid concentrations could diminish the side reactions. We observed intermolecular hydrogen bonding among alcohols and acids could disrupt. Assuming that intermolecular hydrogen bonding accelerates the formation of 1,2-orthoamides
    2-基糖苷的N , N-二乙酰基保护是一种优雅的策略,但由于糖基化中的意外副反应而应用有限。我们发现高酸浓度可以减少副反应。我们观察到醇和酸之间的分子间氢键可能会破坏。假设分子间氢键加速了 1,2-邻酰胺的形成并且破坏分子间氢键可以转变为所需的糖基化,我们成功地在范围广泛的醇受体的糖基化中以及在一个一锅合成受保护的人乳寡糖乳-N-新四糖
