    摘要:
    描述了通过基于预激活的一锅 [2 + 1 + 4] 糖基化策略首次化学合成 B 型 V 族链球菌荚膜多糖 (CPS) 的七糖重复单元。通过使用二醇糖基受体进行区域/立体选择性糖基化反应,进一步提高了合成效率。合成靶标在还原端含有游离氨基,有利于额外的区域选择性加工。该结果对于相关 CPS 的合成和生物学研究应该有用。

    Acyl and Silyl Group Effects in Reactivity-Based One-Pot Glycosylation: Synthesis of Embryonic Stem Cell Surface Carbohydrates Lc4 and IV2Fuc-Lc4
    摘要:
    Relative reactivity evaluations showed the graded arming of toluenyl thioglucosides by variously positioned silyl groups but not by their acyl counterparts. These findings were applied in reactivity-based one-pot assembly of linker-attached Lc(4) and IV(2)Fuc-Lc(4), which are components of human embryonic stem cell surface. The sugar-galectin-1 binding was also examined.

  • One-Pot Synthesis of the Repeating Unit of Type VII Group B <i>Streptococcus</i> Polysaccharide and the Dimer

    日期:2019.4.5
    The first synthesis of the hexasaccharide repeating unit of type VII group B Streptococcus capsular polysaccharide was achieved by a one-pot glycosylation strategy. The dimer of this repeating unit was also synthesized by one-pot glycosylation to achieve the backbone hexasaccharide first followed by one-pot dual glycosylations with the side-chain trisaccharide donor. All glycosylation reactions gave
    VII型B组链球菌荚膜多糖的六糖重复单元的首次合成是通过单罐糖基化策略实现的。还通过一锅糖基化合成该重复单元的二聚体,以首先获得主链六糖,然后与侧链三糖供体一锅双糖基化。所有糖基化反应均具有出色的立体选择性,这利用了新的立体特异性α-糖基化方法和邻基团对1,2-反式糖基化的参与作用。
  • Stereoselective synthesis of the 3,6-branched Fuzi α-glucans up to 15-mer via a one-pot and convergent glycosylation strategy

    A family of the 3,6-branched Fuzi α-glucans including the pentasaccharide repeating unit as well as its di- and trimers were efficiently achieved via a one-pot and convergent glycosylation strategy. All the protected α-glucans up to 15-mer were assembled with high yields and excellent α-stereoselectivity, which was secured by the synergistic α-directing effects of the TolSCl/AgOTf promotion system
    一个 3,6-支链附子α-葡聚糖家族,包括五糖重复单元及其二聚体和三聚体,是通过一锅法收敛糖基化策略有效实现的。所有高达 15 聚体的受保护α-葡聚糖均以高产率和出色的α-立体选择性组装,这是由TolSCl/AgOTf 促进系统的协同α-定向作用和大体积糖残基的空间β-面屏蔽所确保的连接在糖基供体的6- O-位。此外,糖基供体的 3,6 分支结构被发现更有利于α-伯羟基的选择性糖苷化,特别是在大寡糖受体的情况下。结构明确的合成α -葡聚糖可用于各种生物学研究。
