  • N-Heterocyclic silylene/germylene ligands in Au(<scp>i</scp>) catalysis

    Cationic Au(I) complexes (2, 5 and 8) supported by N-heterocyclic carbene, silylene and germylene ligands were prepared and their potential as catalysts in glycosidation chemistry has been evaluated. Insights into the mechanism are provided using DFT studies. Practical application of them as catalysts was achieved by the synthesis of the branched pentamannan core of the HIV-gp120 envelope under mild
    制备了由N-杂环卡宾,亚甲硅烷基和亚二甲苯配体支撑的阳离子Au(I)配合物(2、5和8),并评估了它们在糖苷化学中作为催化剂的潜力。使用DFT研究提供了对该机制的见解。通过在温和条件下合成HIV-gp120包膜的支链五聚甘露聚糖核心,可以将它们实际用作催化剂。
  • Nucleofuge Generating Glycosidations by the Remote Activation of Hydroxybenzotriazolyl Glycosides

    by the extrusion of the oxocarbenium ion that was attacked by the glycosyl acceptor. Further, equilibration of the zwitterionic benzotriazolyl species makes the leaving group noncompetitive and generates the nucleofuge that has been reconverted to the glycosyl donor. The reaction is mild, high yielding, fast and suitable for donors containing both C2-ethers and C2-esters as well. The regenerative-donor
    羟基苯并三唑因其增加的反应性而通常用于肽化学中,以减少外消旋作用。在本文中,鉴定出非常稳定的羟基苯并三唑葡糖苷可以进行糖苷化。假设该反应通过Tf 2进行远程激活在HOBt的N3位点为O,接着是被糖基受体攻击的氧碳鎓离子的挤出。此外,两性离子苯并三唑基物质的平衡使离去基团失去竞争性,并产生已被重新转化为糖基供体的核沉子。该反应温和,高产率,快速并且适合于同时含有C2-醚和C2-酯的供体。再生供体糖苷化策略是有前途的,因为它使我们能够再生糖基供体以供进一步利用。通过成功合成HIV1-gp120复合物的支链五聚甘露聚糖核心,证明了该方法在寡糖合成中的实用性。
  • Chemoenzymatic synthesis of l-galactosylated dimeric Sialyl Lewis X structures employing α-1,3-fucosyltransferase V

    L-Galactosylated dimeric sialyl Lewis X (SLeX) has been prepared employing a combination of chemical and enzymatic synthetic methods. GDP-L-galactose has been chemically synthesised. Enzymatic transfer of L-galactose onto the acceptor (Sia-alpha2,3-Gal-beta1,4-GlcNAc-beta1,3/6)2-Man-alpha1-OMe was achieved using the human alpha-1,3-fucosyltransferase V.

    作者:Antonello Pastore、Matteo Adinolfi、Alfonso Iadonisi、Silvia Valerio
    DOI:10.1002/ejoc.200901122
    日期:2010.2
    The removal of a transient Fmoc protecting group can be simply performed by the addition of excess Et 3 N just after the accomplishment of a Bi(OTf) 3 -promoted glycosidation reaction. The obtained oligosaccharide can be directly employed as a glycosyl acceptor for further elongation of the saccharide. The preparation of biologically important, linear and branched mannans incorporated into HIV gp120
    在 Bi(OTf) 3 促进的糖苷化反应完成后,通过添加过量的 Et 3 N 可以简单地去除瞬时 Fmoc 保护基团。得到的寡糖可以直接作为糖基受体进一步延伸糖类。纳入 HIV gp120 的生物学上重要的线性和分支甘露聚糖的制备表明,这种单锅序列的迭代导致了非常简单的寡糖组装。
  • Rapid assembly of gp120 oligosaccharide moieties via one-pot glycosidation–deprotection sequences

    as a glycosyl acceptor for further elongation. The preparation of biologically important linear and branched oligomannoses incorporated into HIV gp120 demonstrates that iteration of this one-pot sequence leads to very straightforward oligosaccharide assembly. As an additional result, a rapid approach has been disclosed for accessing a 3,6-OH mannose building-block to be incorporated in branched structures
    装备有2-O-Fmoc基团的甘露糖基三卤代乙酰乙酸供体可通过糖基化反应中的催化Bi(OTf)(3)有效激活。尽管Fmoc基团有预期的参与作用,但发现反应溶剂对于获得高度选择性的α-甘露糖基化起决定性作用。然后可以在进行糖苷化的同一容器中,简单地从获得的二寡糖中除去Fmoc 2-O-保护基。所得的寡糖因此可以直接用作糖基受体以进一步延长。整合入HIV gp120的具有生物学重要性的线性和支链低聚甘露糖的制备表明,这一一锅法序列的迭代可导致非常简单的寡糖组装。另外的结果是,公开了一种访问3的快速方法,6-OH甘露糖构建基要结合到支链结构中。这依赖于二-O-亚苄基甘露糖中间体的双重还原开口,其区域选择性似乎与五元亚苄基的构型无关。
