  • Palladium(<scp>ii</scp>)-assisted activation of thioglycosides
    作者:Samira Escopy、Yashapal Singh、Alexei V. Demchenko
    DOI:10.1039/d1ob00004g
    日期:——
    Described herein is the first example of glycosidation of thioglycosides in the presence of palladium(II) bromide. While the activation with PdBr2 alone was proven feasible, higher yields and cleaner reactions were achieved when these glycosylations were performed in the presence of propargyl bromide as an additive. Preliminary mechanistic studies suggest that propargyl bromide assists the reaction
    本文描述的是在溴化钯( II )存在下硫代糖苷的糖苷化的第一个实例。虽然单独使用 PdBr 2进行活化已被证明是可行的,但当这些糖基化在炔丙基溴作为添加剂存在的情况下进行时,可以实现更高的产率和更清洁的反应。初步机理研究表明,炔丙基溴通过产生电离络合物来促进反应,从而加速离去基团的离开。研究了与不同糖基受体反应的各种硫代糖苷供体,以确定这种新反应的初始范围。还探索了硫代糖苷相对于其他离去基团的选择性和化学选择性激活。
  • A Streamlined Regenerative Glycosylation Reaction: Direct, Acid‐Free Activation of Thioglycosides
    作者:Samira Escopy、Yashapal Singh、Keith J. Stine、Alexei V. Demchenko
    DOI:10.1002/chem.202003479
    日期:2021.1.4
    (HOFox) is able to mediate glycosylations via intermediacy of OFox imidates. Thioglycoside precursors were first converted into the corresponding glycosyl bromides that were then converted into the OFox imidates in the presence of Ag2O followed by the activation with catalytic Lewis acid in a regenerative fashion. Reported herein is a direct conversion of thioglycosides via the regenerative approach
    我们的小组之前曾报道过,3,3-二氟吲哚(HOFox)能够通过 OFox 亚胺酸酯的中介来介导糖基化。硫糖苷前体首先转化为相应的糖基溴化物,然后在 Ag 2 O存在下转化为 OFox 亚胺酸酯,然后以再生方式用催化路易斯酸活化。本文报道了通过再生方法直接转化硫糖苷,该方法绕过了溴化物的中介并消除了对基于重金属的促进剂的需要。在中性反应条件下仅使用 1 当量即可实现硫糖苷的直接再生活化。不含酸性添加剂的 NIS 和催化 HOFox。
  • Ionic Liquid [bmim]PF<sub>6</sub>-Mediated Synthesis of 1,2-Orthoesters of Carbohydrates and the Glycosidation Reactions of 4-Pentenyl Orthoesters
    作者:Saithalavi Anas、Valiyaveetil Sanjayan Sajisha、Rani Rajan、Rajasekaran Thirumalai Kumaran、Kokkuvayil Vasu Radhakrishnan
    DOI:10.1246/bcsj.80.553
    日期:2007.3.15
    A facile synthesis of the 1,2-orthoesters of carbohydrates in the ionic liquid [bmim]PF6 without a quaternary ammonium salt like tetrabutylammonium iodide, is described. The glycosidation reactions of 4-pentenyl orthoesters (NPOEs) with different alcohols are also discussed. The work described in this paper showed that [bmim]PF6 is an efficient and recyclable solvent for the synthesis and glycosidation reaction of orthoesters.
    描述了一种在离子液体[bmim]PF6中合成糖类1,2-邻醚的简便方法,无需使用四丁基氨铵盐如碘化四丁基铵。还讨论了4-戊烯基邻醚(NPOEs)与不同醇的糖苷化反应。本文所述的工作表明,[bmim]PF6是一种高效且可回收的溶剂,用于邻醚的合成和糖苷化反应。
  • Preparation, Properties, and Applications of <i>n</i>-Pentenyl Arabinofuranosyl Donors
    作者:Jun Lu、Bert Fraser-Reid
    DOI:10.1021/ol0490680
    日期:2004.9.1
    development of n-pentenyl furanosyl donors has been tested using arabinose as a model. The readily prepared ortho ester (NPOE) is converted into disarmed (NPG(AC)) and thence armed (NPG(ALK)) n-pentenyl arabinofuranosides. The reactivities of these furanosyl donors and pyranosyl counterparts have been assessed by allowing pairs of both to compete for an acceptor. For the NPOE and armed (NPG(ALK)) pairs
    [反应:见正文]已使用阿拉伯糖作为模型测试了正戊烯基呋喃糖基供体的发育。易于制备的原酸酯(NPOE)被转化为脱甲(NPG(ACK)),然后被武装(NPG(ALK))正戊烯基阿拉伯呋喃糖苷。这些呋喃糖基供体和吡喃糖基对应物的反应性已经通过允许两者成对竞争竞争受体来评估。对于NPOE和武装(NPG(ALK))对,从供体中获得偶联产物,而对于解除武装(NPG(AC))对,仅获得阿拉伯呋喃诺偶联产物。为了探究其合成用途,已证明NPOE是制备结核分枝杆菌复杂lipoarabinomannan细胞壁阵列的α-1,5-连接的阿拉伯聚糖片段所需的唯一前体。
  • Microwave-assisted saccharide coupling with n-pentenyl glycosyl donors
    作者:Felix Mathew、K.N. Jayaprakash、Bert Fraser-Reid、Jessy Mathew、Jan Scicinski
    DOI:10.1016/j.tetlet.2003.09.206
    日期:2003.12
    n-Pentenyl glycosides, armed and disarmed, and n-pentenyl orthoesters couple with acceptors, hindered and unhindered, within 25 min under microwave activation. The reaction takes place in acetonitrile under neutral conditions with N-iodosuccinimide as promotor, which are therefore ideal for use with reactants bearing acid-labile protecting groups.
    在微波激活下25分钟内,已武装和已解除武装的n-戊烯基糖苷和受阻和不受阻碍的n-戊烯基原酸酯与受体的结合。反应在乙腈中以N-碘代琥珀酰亚胺为促进剂在中性条件下进行,因此非常适合与带有酸不稳定保护基的反应物一起使用。
