  • An Empirical Understanding of the Glycosylation Reaction
    作者:Sourav Chatterjee、Sooyeon Moon、Felix Hentschel、Kerry Gilmore、Peter H. Seeberger
    DOI:10.1021/jacs.8b04525
    日期:2018.9.26
    Reliable glycosylation reactions that allow for the stereo- and regioselective installation of glycosidic linkages are paramount to the chemical synthesis of glycan chains. The stereoselectivity of glycosylations is exceedingly difficult to control due to the reaction's high degree of sensitivity and its shifting, simultaneous mechanistic pathways that are controlled by variables of unknown degree
    允许立体和区域选择性安装糖苷键的可靠糖基化反应对于聚糖链的化学合成至关重要。糖基化的立体选择性极难控制,因为该反应具有高度的敏感性,而且其变化的、同步的机械途径受未知程度的影响、优势或相互依赖的变量控制。设计了一个自动化平台来快速、可重复和系统地筛选糖基化,从而解决这个基本问题。以尽可能孤立的方式研究了 13 个变量,以识别和量化亲电糖基化试剂(糖基供体)和亲核试剂(糖基受体)的固有偏好。增强、抑制、甚至发现使用明智的环境条件覆盖这些偏好。只需改变反应条件,就可以调整涉及两个特定伙伴的糖基化,以产生一种立体异构体的 11:1 选择性或另一种立体异构体的 9:1 选择性。
  • Tris(pentafluorophenyl)borane-Promoted Stereoselective Glycosylation with Glycosyl Trichloroacetimidates under Mild Conditions
    作者:Kunj Bihari Mishra、Adesh Kumar Singh、Jeyakumar Kandasamy
    DOI:10.1021/acs.joc.8b00215
    日期:2018.4.6
    Tris(pentafluorophenyl)borane-promoted stereoselective glycosylation with trichloroacetimidate glycosyl donors is described. The reactions proceed efficiently with a wide range of acceptors, from sugar to nonsugar, under mild conditions in the presence of a catalytic amount of B(C6F5)3. The perbenzylated glucosyl α-imidate provides β-selective glycosides in 70–92% yields.

    摘要糖苷和寡糖的立体选择性合成已引起广泛关注,不仅用于天然产物的制备1,还用于糖的同源化以用作更复杂的合成靶标的手性模板。2目前最新的制备方法3的糖苷是基于异头中心离去基团的活化作用。3已提出了多种(潜在的)离去基团。它们中的一些在没有合适的启动子的情况下是稳定的,并起着临时保护基的作用。3三氟乙酰氧基在异头位置是一个很好的离去基团,在我们的实验室中,C,O,S和N-糖苷4和寡糖5均使用含有该基团的衍生物以高立体选择性合成。然而,发现三氟乙酸糖基酯反应性太强,并且研究了含有三乙酰氧基离去基团的新的糖基供体。我们现在报告立体声音响...
  • Novel Stereocontrolled Glycosidations Using a Solid Acid, SO<sub>4</sub>/ZrO<sub>2</sub>, for Direct Syntheses of <i>α</i>- and <i>β</i>-Mannopyranosides
    作者:Kazunobu Toshima、Ken-ichi Kasumi、Shuichi Matsumura
    DOI:10.1055/s-1998-1741
    日期:1998.6
    Novel stereocontrolled glycosidations using an environmentally friendly solid acid, sulfated zirconia (SO4/ZrO2), for direct syntheses of α- and β-mannopyranosides have been developed. The glycosidations of the totally benzylated mannopyranosyl fluoride 1 and various alcohols using SO4/ZrO2 in CH3CN at 40 °C for 15 h exclusively gave the corresponding α-mannopyranosides. On the other hand, the corresponding β-mannopyranosides were selectively obtained by the glycosidations of 1 and various alcohols employing SO4/ZrO2 in the presence of molecular sieves 5 Å in Et2O at 25 °C for 15 h.
    使用环保固体酸硫酸氧化锆 (SO4/ZrO2) 的新型立体控制糖苷化,用于直接合成 α- 和 β- 甘露糖苷,已经开发出来。完全苄基化的甘露糖化物 1 和各种醇在 CH3CN 中于 40 °C 下使用 SO4/ZrO2 进行糖苷化 15 小时,专门得到相应的 α-甘露糖苷。另一方面,相应的β-甘露糖苷是通过1 和各种醇的糖苷化选择性获得的,使用SO4/ZrO2 在分子筛5 Å 的Et2O 存在下在25 °C 15 小时。
  • A glycosylation reaction: Conversion of methyl glicosides to glycosyl chlorides by boron trichloride
    作者:Guillermo R. Perdomo、Jiri J. Krepinsky
    DOI:10.1016/s0040-4039(00)96789-3
    日期:1987.1
    Methyl glycosides react readily with boron trichloride in dichloromethane solutions at −78 °C to give the corresponding glycosyl chlorides for subsequent use in glycosylation reactions. This reaction is compatible with the presence of glycosyl linkages in the molecule, as well as benzyl and acetyl protecting groups.
    甲基糖苷在-78°C的二氯甲烷溶液中容易与三氯化硼反应,得到相应的糖基化物,随后用于糖基化反应。该反应与分子中糖基键以及苄基和乙酰基保护基团的存在相容。
