  • Influence of Steric Crowding on Diastereoselective Arabinofuranosylations
    作者:Maidul Islam、Gaddamanugu Gayatri、Srinivas Hotha

    日期:2015.8.21
    their significance in controlling disease spurred interest in developing strategies for their diastereoselective synthesis. Mtb uses enzymes to achieve diastereoselectivity through noncovalent interactions. Of the two possible glycosidic linkages, chemically, 1,2-trans linkage is relatively easy to synthesize by taking advantage of neighboring group participation, whereas synthesis of the 1,2-cis linkage
    结核分枝杆菌(Mtb)细胞表面上阿拉伯呋喃糖苷的出现及其在控制疾病中的意义激发了人们开发非对映选择性合成策略的兴趣。Mtb使用酶通过非共价相互作用实现非对映选择性。在两个可能的糖苷键中,化学上,1,2-反式键相对容易通过利用邻近基团的参与来合成,而1,2-顺式的合成链接非常困难。在本文中,用硫代吡啶基,亚氨酸酯和硫代甲苯基供体以及拥挤程度不同的糖基受体研究了立体化学对阿拉伯呋喃糖基化非对映选择性的影响。观察到受体的立体化学环境存在细微差异,从而改变了呋喃糖苷形成的非对映选择性。该努力的结果表明,可以通过在较低温度下在对空间要求高且反应性较低的底物上进行反应来方便地合成1,2-顺式阿拉伯呋喃糖苷。
  • Stereoselective 1,2-<i>cis</i> Furanosylations Catalyzed by Phenanthroline

    furanosylation method promoted by phenanthroline catalysts under mild and operationally simple conditions. NMR experiments and density functional theory calculations support an associative mechanism in which the rate-determining step occurs from an inverted displacement of the faster-reacting phenanthrolinium ion intermediate with an alcohol nucleophile. The phenanthroline catalysis system is applicable
    1,2-顺式呋喃糖苷键的立体选择性形成,许多生物学相关的寡糖和多糖的基序,仍然是一个重要的合成挑战。我们在此报告了一种由菲咯啉催化剂在温和且操作简单的条件下促进的新立体选择性 1,2-顺式呋喃基化方法。NMR 实验和密度泛函理论计算支持一种关联机制,其中速率决定步骤发生在反应较快的菲咯啉离子中间体与醇亲核试剂的反向置换中。菲咯啉催化系统适用于许多呋喃糖基溴供体,以提供具有挑战性的 1,2-顺式具有高异头异构体选择性的高产率取代产物。虽然阿拉伯呋喃糖基溴提供 β-1,2-顺式产品,但木糖和呋喃核糖基溴有利于 α-1,2-顺式产品。
  • Stereospecific Furanosylations Catalyzed by Bis-thiourea Hydrogen-Bond Donors
    作者:Andrew B. Mayfield、Jan B. Metternich、Adam H. Trotta、Eric N. Jacobsen
    DOI:10.1021/jacs.0c00335
    日期:2020.2.26
    We report a new method for stereoselective O-furanosylation reactions promoted by a precisely tailored bis-thiourea hydrogen-bond-donor catalyst. Furanosyl donors outfitted with an anomeric dialkylphosphate leaving group undergo substitution with high anomeric selectivity, providing access to the challenging 1,2-cis substitution pattern with a range of alcohol acceptors. A variety of stereochemically distinct, benzyl-protected glycosyl donors were engaged successfully as substrates. Mechanistic studies support a stereospecific mechanism in which rate-determining substitution occurs from a catalyst-donor resting-state complex.
  • Acceptor-Dependent Stereoselective Glycosylation:  2‘-CB Glycoside-Mediated Direct β-<scp>d</scp>-Arabinofuranosylation and Efficient Synthesis of the Octaarabinofuranoside in Mycobacterial Cell Wall
    作者:Yong Joo Lee、Kyunghoon Lee、Eun Hye Jung、Heung Bae Jeon、Kwan Soo Kim
    DOI:10.1021/ol0510668
    日期:2005.7.1
    A reliable and generally applicable direct method for the stereoselective beta-arabinofuranosylation employing a 2'-carboxybenzyl arabinofuranoside as the glycosyl donor has been established. The acyl-protective group on glycosyl acceptors is essential for the beta-stereoselectivity. The power of the present acceptor-dependent glycosylation method was demonstrated by the efficient synthesis of the octaarabinofuranoside in arabinogalactan and lipoarabinomannan found in mycobacterial cell wall.
  • Arabinofuranosides from Mycobacteria:  Synthesis of a Highly Branched Hexasaccharide and Related Fragments Containing β-Arabinofuranosyl Residues
    作者:Haifeng Yin、Francis W. D'Souz、Todd L. Lowary
    DOI:10.1021/jo010910e
    日期:2002.2.1
    The synthesis of 11 oligosaccharides (4-14) containing beta-arabinofuranosyl residues is reported. The glycans are all fragments of two polysaccharides, arabinogalactan and lipoarabinomannan, which are found in the cell wall complex of mycobacteria. In the preparation of the targets, the key step was a low-temperature glycosylation reaction that installed the beta-arabinofuranosyl residues with good
