  • Thio and epidithio derivatives of methyl β-lactoside
    作者:Mezher A. Ali、Leslie Hough、Anthony C. Richardson

    日期:1992.9
    3′,6′-anhydro-6-bromo-6-deoxy derivative, from which 6-thio derivatives were prepared, and methyl 3′,4′-O-isopropylidene-β-lactoside gave the 6,6′-dibromo-6,6′-dideoxy derivative. A dibromide was prepared also from methyl 4′,6′-O-benzylidene-β-lactoside by bromination with Ph3P-CBr4, acetylation, and then treatment with N-bromosuccinimide. Various 6,6′-dithio derivatives were prepared from the 6,6′-dibromide
    摘要用三苯基膦-四溴化碳吡啶中处理甲基β-乳糖苷,得到3',6'-脱-6--6-脱氧衍生物,制备了6-代衍生物,甲基3',4'- O-异亚丙基-β-乳糖苷得到6,6'-二-6,6'-二脱氧衍生物。也由甲基4′,6′-O-亚苄基-β-乳糖苷通过用Ph 3 P-CBr 4化,乙酰化,然后用N-代琥珀酰亚胺处理来制备二化物。通过亲核取代反应从6,6'-二化物制备了各种6,6'-二代衍生物。6,6′-二化物与硫脲的反应产生6,6′-表二代衍生物,并与三硫代碳酸钾形成桥连的6,6′-三硫代碳酸酯。对6,6'-二生物进行选择性亲核取代,得到各种6'--6-代衍生物。同样地,用叠氮化物首先形成6-叠氮化物,然后形成6,6'-二叠氮化物和消除的产物6-叠氮基-5'-烯。阮内介导的各种6,6'-二代衍生物的脱得到甲基6,6'-二脱氧-β-乳糖苷,并且可以实现6'--6

    (β-d-glucopyranosyl) rings in (I) adopt slightly distorted 4C1 chair conformations, with the former distorted towards a boat form (BC1,C4) and the latter towards a twist-boat form (O5SC2). Puckering parameters for (I) and (II) indicate that the conformation of the βGalp ring is slightly more affected than the βGlcp ring by the solvomorphism. Conformations of the terminal O-glycosidic linkages in (I) and (II)

  • Fast and efficient synthesis of a novel homologous series of l-fucosylated trisaccharides using the Helix pomatia α-(1→2)-l-galactosyltransferase
    作者:Angela Michelle Scheppokat、Hagen Bretting、Joachim Thiem
    DOI:10.1016/s0008-6215(03)00344-6
    日期:2003.9
    The alpha-(1-->2)-L-galactosyltransferase from the albumen gland of the vineyard snail Helix pomatia exhibits high alpha-(1-->2)-L-fucosyltransferase activity and can be used to transfer L-fucose from GDP-L-fucose to terminal, non-reducing D-galactose residues of an oligosaccharide, thus providing facile access to a range of H-antigen-containing oligosaccharides. The enzymatic glycosylation was applied
    来自葡萄园蜗牛螺旋藻的蛋白腺的α-(1-> 2)-L-半乳糖基转移酶表现出高的α-(1-> 2)-L-岩藻糖基转移酶活性,可用于从中转移L-岩藻糖GDP-L-岩藻糖可连接至寡糖的末端非还原D-半乳糖残基,因此可轻松接入各种含H抗原的寡糖。酶促糖基化在这里以毫克级施加到一系列二糖受体底物上。显然,末端和亚末端受体糖单元之间糖苷间键合的位置几乎没有影响。由此产生的三糖的同源系列通过其过乙酸盐的NMR分析得到充分表征。
  • Tandem Acetalation−Acetylation of Sugars and Related Derivatives with Enolacetates under Solvent-Free Conditions
    作者:Debaraj Mukherjee、Bhahwal Ali Shah、Pankaj Gupta、Subhash Chandra Taneja
    DOI:10.1021/jo070363i
    日期:2007.11.1
    [GRAPHICS]Molecular iodine catalyzes acetalation and acetylation of reducing sugars and sugar glycosides with stoichiometric amounts of enol acetates under solvent-free conditions, thereby facilitating the synthesis of various types of orthogonally protected sugar derivatives in short time and good yields. The outcome of the reaction can be controlled by variation in temperature. Thus at lower temperature, it is possible to obtain the acetonide acetate as a single product whereas peracetate is the major product at higher temperature.
  • A Multifunctional <i>Pasteurella multocida</i> Sialyltransferase:  A Powerful Tool for the Synthesis of Sialoside Libraries
    作者:Hai Yu、Harshal Chokhawala、Rebekah Karpel、Hui Yu、Bingyuan Wu、Jianbo Zhang、Yingxin Zhang、Qiang Jia、Xi Chen
    DOI:10.1021/ja0561690
    日期:2005.12.1
    A multifunctional sialyltransferase has been cloned from Pasteurella multocida strain P-1059 and expressed in E. coli as a truncated C-terminal His6-tagged recombinant protein (tPm0188Ph). Biochemical studies indicate that the obtained protein is (1) an alpha2,3-sialyltransferase (main function), (2) an alpha2,6-sialyltransferase, (3) an alpha2,3-sialidase, and (4) an alpha2,3-trans-sialidase. The recombinant tPm0188Ph is a powerful tool in the synthesis of structurally diverse sialoside libraries due to its relaxed substrate specificity, high solubility, high expression level, and multifunctionality.
