    method. ortho-Formylphenyl 1-thio-β-d-galactopyranoside was regioselectively tethered to methyl α-d-glucopyranoside under acidic condition to furnish an 4,6-O-arylidene acetal-linked conjugate. This conjugate can be readily converted to an ether-linked 4-O- or 6-O-derivative by regioselective cleavage of the acetal ring. In the glycosylation reaction, the ether-linked 4-OH conjugate was found to show excellent
    提出了一种简便的方法,用于糖基供体和受体之间的区域选择性缀合,以发展区域选择性1,2-顺式糖基化方法。在酸性条件下,将邻甲酰基苯基1-代-β-d-喃半乳糖苷区域选择性地束缚在甲基α-d-葡萄糖苷上,得到4,6-O-亚芳基乙缩醛连接的共轭物。通过缩醛环的区域选择性裂解,该缀合物可以容易地转化为醚连接的4-O-或6-O-衍生物。在糖基化反应中,发现通过分子内的1,9-转移,醚连接的4-OH缀合物显示出优异的1,2-顺式选择性。

  • Convenient use of non-malodorous thioglycosyl donors for the assembly of multivalent globo- and isoglobosyl trisaccharides

    New thioglycosyl donors (o-methoxycarbonylphenyl 2,3,4,6-tetra-O-benzyl-1-thio-beta-D-galactopyranoside and its 6-O-acetyl analogue) were designed and used for the synthesis of glycoconjugate polymers carrying Gb(3) [Gal(alpha1-->4)Gal(beta1-->4)Glc] and isoGb(3) [Gal(alpha1-->3)Gal(beta1-->4)Glc] clusters as side chains. These donors scarcely evolved the unpleasant odor of thiophenols and showed a high alpha-anomeric selectivity in the galactosylation of p-nitrophenyl beta-lactoside derivatives, although in moderate yields. The derived trisaccharides were converted to multivalent carbohydrate ligands and were subjected to a biological assay with Shiga toxins. The multivalent Gb(3) ligand was highly active in inhibiting the toxicity, while the isoGb(3) ligand showed no activity, indicating that Stx-I discriminates between the carbohydrate structures.
