  • Synthesis of 5-aminopentyl 4,6-O-[(R)-1-carboxyethylidene]-β-d-galactopyranoside and its use as a ligand for the affinity chromatography of human serum amyloid P protein
    作者:Thomas Ziegler、Elisabeth Eckhardt、Jochen Strayle、Helmut Herzog

    日期:1994.2
    corresponding protected beta-D-galactoside 27, deblocking of which afforded the title compound 1. Binding of 1 to epoxypropyl-modified acrylamide beads gave an affinity adsorbent that was used to isolate serum amyloid P protein from human serum.

  • Rhizobial saccharides 2. Selective synthesis of both diastereomers of 4,6-O-pyruvylated d-glycopyranosides
    作者:Thomas Ziegler
    DOI:10.1016/0040-4039(94)85023-2
    日期:1994.9
    Both diastereomers of 4,6-O-pyruvylated glycosides S- and R - 2 were selectively prepared from the corresponding 4,6-unprotected glycosides 1 by acetalation of the latter with methyl pyruvate and BF3-diethylether complex. In acetonitrile as the solvent, the thermodynamically favoured diastereomers having an axial-oriented methoxycarbonyl group are formed preferentially. In methyl pyruvate as the solvent

  • Diastereoselective formation of pyruvylated glycosides from partly protected sugars and methyl pyruvate

    日期:1992.7
    Various partly protected sugars (gluco-, manno-, and galactopyranosides) were acetalized with methyl pyruvate in moderate to good yield with BF3-etherate as the condensing reagent. Thus, (1-methoxycarbonyl)ethylidene glycosides were obtained diastereoselectivity.

    海洋海绵Microciona prolifera中物种特异性的细胞粘附涉及细胞外蛋白聚糖样大分子复合物(也称为聚集因子)的相互作用。在相互作用中,两个高度多价的功能域发挥作用:细胞结合域和自我相互作用域。自我识别已被表征为重复低亲和力碳水化合物表位的Ca(2+)依赖性碳水化合物相互作用。涉及的表位之一是丙酮酸三糖β-d-Galp4,6(R)Pyr-(1→4)-β-d-GlcpNAc-(1→3)-1-Fucp。为了评估这种三糖在蛋白聚糖-蛋白聚糖自我识别中的作用,β-d-Galp4,6(R)Pyr-(1-> 4)-beta-d-GlcpNAc-(1-> 3)-合成了α-1-Fucp-(1-> O)(CH(2))(3)S(CH(2))(6)SH,并部分转化为金纳米颗粒。这些模拟物被用于通过TEM聚集实验(金纳米颗粒)和原子力显微镜(AFM)实验(自组装单层;结合力)来探索三糖表位的自相互作用现象。
  • Total Synthesis of Zwitterionic Tetrasaccharide Repeating Unit from <i>Bacteroides fragilis</i> ATCC 25285/NCTC 9343 Capsular Polysaccharide PS A1 with Alternating Charges on Adjacent Monosaccharides
    作者:Pradheep Eradi、Samir Ghosh、Peter R. Andreana
    DOI:10.1021/acs.orglett.8b01829
    日期:2018.8.3
    The tetrasaccharide repeating unit of zwitterionic polysaccharide A1 (PS A1) from Bacteroides fragilis ATCC 25285/NCTC 9343 has been synthesized using a linear glycosylation approach. One key step includes an alpha(1,4)-stereoselective [2 + 1] glycosylation of a 2,4,6-trideoxy-2-acetamido-4-amino-D-Galp (AAT) donor with a poorly reactive axial C4-OH disaccharide acceptor. Mild acid-mediated deacetylation and a challenging [3 + 1] glycosylation are also highlighted. The strategy is inclusive of a single-pot, three-step deprotection affording PS A1 with alternating charges on adjacent monosaccharide units.
