  • Synthesis of a (1→3)-Linked α-L-Fucose Tetrasaccharide
    作者:Michael Ludewig、Joachim Thiem
    DOI:10.1135/cccc20041768
    日期:——

    Orthoester-protected benzyl and methyl 1-thiofucopyranosides could be opened to give fucopyranosides unblocked at position 3. Convergent glycosylations of such donors and acceptors led to the corresponding disaccharides, and their block condensation could be elaborated to give the (1→3)-linked α-L-fucose tetrasaccharide. Compounds of this structure are of interest with regard to the role of fucose in metastasis development in lung tissue.

    Orthoester保护的苄基和甲基1-硫代富醣苷可以被打开,形成未在位置3上阻断的富醣苷。这些供体和受体的汇合糖基化导致相应的二糖,并且它们的阻断缩合可以详细说明以形成(1→3)-连接的α-L-岩藻糖四糖。这种结构的化合物在肺组织中富醣在转移生成中的作用方面具有重要意义。
  • Synthesis of a Fucose Hexasaccharide
    作者:Michael Ludewig、Joachim Thiem

    日期:1998.1
    The facile synthesis of homogeneously α, 1 → 2 interglycosidically linked fucose hexasaccharide 17 via the disaccharide methylthio donor 10 is reported. Compound 10 in turn was synthesised from a monosaccharide thiomethyl precursor in three consecutive steps. Glycosylation employing thioglycosides activated by copper bromide/tetrabutylammonium bromide proved to be selective for the formation of α-glycosidic linkages.

  • Crystal and molecular structure of methyl α-d-galactopyranoside 4-(sodium sulphate) dihydrate
    作者:Jan A. Kanters、Berend van Dijk、Jan Kroon
    DOI:10.1016/0008-6215(91)84040-l
    日期:1991.6
    Abstract The crystal and molecular structure of methyl α- d -galactopyranoside-4-(sodium sulphate) dihydrate has been determined by X-ray analysis at − 173°. The sugar ring has a distorted 4 C 1 chair conformation. The conformation of the CH 2 OH group is gauche-trans and the bridging SO bond is eclipsed with the C-4H bond, which diminishes the steric repulsion of the sulphate group with the neighbouring
    摘要通过在-173°下的X射线分析确定了α-d-吡喃半乳糖苷-4-(硫酸钠)二水合物的晶体和分子结构。糖环具有扭曲的4 C 1椅构象。CH 2 OH基团的构象是反式的,桥连的SO键被C-4H键遮盖,这减少了硫酸根与相邻CH 2 OH和HO-3基团的空间排斥。钠离子在两倍轴上占据特殊位置,并且每一个都协调六倍。Na-1周围的三个独立的氧原子属于两个不同的硫酸盐氧原子,这些氧原子与两个不同的糖环和其中一个环的O-3相关。在Na-2的配位中,三个独立的氧原子属于水分子之一和一个硫酸盐基团。Na-1的配位接近理想的八面体对称性,而Na-2的配位则明显失真。配位和氢键均导致复杂的堆积模式,其中围绕螺钉的单个氢键螺旋为轴,其中包含羟甲基和水分子,并且几乎与甲基α-d-所观察到的排列相同吡喃半乳糖苷一水合物。
  • The Syntheses of δ-NCS-Butyl α-<scp>l</scp>-Fucosides and Fucobiosides and Their Clustering to Traintennary Glycomimetics
    作者:Thisbe K. Lindhorst、Michael Ludewig、Joachim Thiem
    DOI:10.1080/07328309808001889
    日期:1998.9.1
    L-Fucose is an especially important monosaccharide constituent in eukaryotic glycoconjugates. Its recognition by fucose specific lectins might play an important role in embryonic development, cancer development and metastasis. Therefore it is of great interest to develop potent inhibitors of fucose specific lectins, both to investigate as well as to manipulate the respective interactions. A promising approach to high affinity fucoside ligands is the synthesis of oligovalent fucosyl clusters. The synthesis of isothiocyanato-functionalized spacer alpha-fucosides and fucobiosides is described together with their clustering on tris(2-aminoethyl)amine giving rise to the first thiourea bridged cluster fucosides 14 and 16 in excellent yields.
