  • Low-Concentration 1,2-<i>trans</i>β-Selective Glycosylation Strategy and Its Applications in Oligosaccharide Synthesis
    作者:Chin-Sheng Chao、Chen-Wei Li、Min-Chun Chen、Shih-Sheng Chang、Kwok-Kong Tony Mong
    DOI:10.1002/chem.200901119
    日期:2009.10.19
    This study develops an operationally easy, efficient, and general 1,2‐trans β‐selective glycosylation reaction that proceeds in the absence of a C2 acyl function. This process employs chemically stable thioglycosyl donors and low substrate concentrations to achieve excellent β‐selectivities in glycosylation reactions. This method is widely applicable to a range of glycosyl substrates irrespective of
    这项研究开发了一种易于操作,有效且通用的1,2-反式β-选择性糖基化反应,该反应在没有C2酰基功能的情况下进行。该过程采用化学上稳定的硫糖基供体和低底物浓度,以在糖基化反应中实现出色的β选择性。该方法可广泛应用于各种糖基底物,无论其结构和羟基保护功能如何。碳水化合物化学中这种低浓度的1,2-反式β-选择性糖基化消除了使用高反应性硫糖苷构建1,2-反式的限制β糖苷键。这有利于寡糖合成新策略的设计,如生物学相关的β-(1→6)-葡聚糖三糖,β-连接的Gb 3和isoGb 3衍生物的制备所示。
  • A flexible 1,2-cis α-glycosylation strategy based on in situ adduct transformation

    日期:——
    strategy for a wide range of glycosyl donors and acceptors has been developed, which is based on an in situ adduct transformation protocol. Based on this strategy, both NFM-derived and iodide covalent adducts can be accessed for glycosylation. Using low temperature NMR spectroscopy, the aforementioned glycosyl adducts were detected.

    (Aka) to quantify the nucleophilicity of hydroxyl groups in glycosylation influenced by the steric, electronic and structural effects, providing a connection between experiments and computer algorithms. The subtle reactivity differences among the hydroxyl groups on various carbohydrate molecules can be defined by Aka, which is easily accessible by a simple and convenient automation system to assure
    糖基化反应的立体选择性和产率至关重要,但不可预测。我们已经开发了一个亲核亲核常数(Aka)数据库,用于量化受空间,电子和结构效应影响的糖基化中羟基的亲核性,从而在实验和计算机算法之间建立联系。各种碳水化合物分子上的羟基之间的细微反应性差异可以由Aka定义,Aka可以通过简单便捷的自动化系统轻松访问,以确保高重现性和准确性。通过设计的软件程序“ GlycoComputer”可以组织和处理各种具有明确反应性和启动子的糖基化供体和受体,从而无需复杂的计算过程即可预测糖基化反应。通过随机森林算法进一步验证了Aka的重要性,并通过合成Lewis A骨架测试了适用性,表明可以准确估计立体选择性和产率。
  • Stereoselective Glycosylations of 2-Azido-2-deoxy-glucosides Using Intermediate Sulfonium Ions
    作者:Jin Park、Sameer Kawatkar、Jin-Hwan Kim、Geert-Jan Boons
    DOI:10.1021/ol070513b
    日期:2007.5.1
    computation studies have shown that these glycosylations proceed through an equatorial anomeric sulfonium ion, which upon displacement by a sugar alcohol provides an axial glycoside. Computational studies have indicated that steric factors determine the selective formation of the beta-anomeric sulfonium ion.
    当在PhSEt或噻吩的存在下在相对较高的反应温度下进行时,TMSOTf促进的2-叠氮基-2-脱氧葡萄糖基三氯乙酰基亚氨酸酯的糖基化反应提供了出色的α-异头异构体选择性。NMR和计算研究表明,这些糖基化过程是通过赤道异头sulf离子进行的,该离子在被糖醇置换后会提供一个轴向糖苷。计算研究表明,空间因素决定了β-异头sulf离子的选择性形成。
  • A stereocontrolled construction of 2-azido-2-deoxy-1,2-trans-β-glycosidic linkages utilizing 2-azido-2-deoxyglycopyranosyl diphenyl phosphates
    作者:Toshifumi Tsuda、Seiichi Nakamura、Shunichi Hashimoto
    DOI:10.1016/s0040-4039(03)01557-0
    日期:2003.8
    A high-yielding and stereocontrolled construction of 2-azido-2-deoxy-1,2-trans-beta-glycosidic linkages has been achieved by exploiting TMSOTf-promoted 1,2-trans-glycosidation of 2-azido-2-deoxyglycopyranosyl diphenyl phosphates with various glycoside alcohols in propionitrile at -78degreesC. The present method exhibits the highest levels of 1,2-trans-beta-selectivity reported to date for this type of glycosidation. (C) 2003 Elsevier Ltd. All rights reserved.
