    Stereoselective Synthesis of a Sulfated Tetrasaccharide Corresponding to a Rare Sequence in the Galactofucan Isolated from Sargassum polycystum
    摘要:
    The first chemical synthesis of a highly sulfated tetrasaccharide 1, as the rare sequence in the galactofucan isolated from the brown alga Sargassum polycystum, was achieved in a convergent and stereoselective manner. The key features of the synthetic strategy include construction of multiple contiguous 1,2-cis glycosidic bonds and [2 + 2] assembly based on the rationally developed D-galactose building block 6. The synthesized oligosaccharides were fully characterized using a combination of coupled-HSQC and other 2D NMR techniques.

  • Multi-Component One-Pot Synthesis of the Tumor-Associated Carbohydrate Antigen Globo-H Based on Preactivation of Thioglycosyl Donors

    same molecule can be constructed in one pot via a preactivation based approach with higher glyco-assembly efficiencies than the automated solid-phase synthesis strategy. Furthermore, because glycosylations can be carried out independent of anomeric reactivities of donors, it is not necessary to differentiate anomeric reactivities of building blocks through extensive protective group adjustment for
    快速组装肿瘤相关碳水化合物抗原Globo-H六糖2的两种有效途径通过基于预激活的迭代一锅策略进行了报道。第一种方法涉及四个糖基结构单元的顺序偶联,从而在一锅合成中以47%的总收率产生所需的六糖。尽管在Gb3三糖中构建具有挑战性的Gal-α-(1-4)-Gal键的模型研究几乎仅产生了所需的α键,但组装六糖的相似方法导致形成了大量的β异头物。作为替代方案,第二种合成在一个锅中利用了三种成分,并预先形成了Gal-α-(1-4)-Gal键,从而以与四成分方法相似的总收率生产了所需的六糖。两种方法均表明,通过基于预激活的方法,与自动固相合成策略相比,具有更高的糖组装效率,可以在一个罐中构建在同一分子中包含α和β键的寡糖。此外,由于糖基化可以独立于供体的端基异构体反应性进行,因此不需要通过针对化学选择性糖基化的广泛保护基调节来区分构件的端基异构体反应性。这赋予了构件设计极大的灵活性,使供体与受体匹配,

    We described the chemical synthesis of a sulfated trisaccharide repeating unit of fucosylated chondroitin sulfate (FCS), which has significant anticoagulant activity. Well-functionalized monosaccharides were readily prepared, and highly efficient glycosylations using a common activator (NIS/TfOH) were also presented. The synthesized trisaccharide 4 could be used to extend oligosaccharide sequences

  • Low-Concentration 1,2-<i>trans</i>β-Selective Glycosylation Strategy and Its Applications in Oligosaccharide Synthesis
    作者:Chin-Sheng Chao、Chen-Wei Li、Min-Chun Chen、Shih-Sheng Chang、Kwok-Kong Tony Mong
    DOI:10.1002/chem.200901119
    日期:2009.10.19
    This study develops an operationally easy, efficient, and general 1,2‐trans β‐selective glycosylation reaction that proceeds in the absence of a C2 acyl function. This process employs chemically stable thioglycosyl donors and low substrate concentrations to achieve excellent β‐selectivities in glycosylation reactions. This method is widely applicable to a range of glycosyl substrates irrespective of
    这项研究开发了一种易于操作,有效且通用的1,2-反式β-选择性糖基化反应,该反应在没有C2酰基功能的情况下进行。该过程采用化学上稳定的硫糖基供体和低底物浓度,以在糖基化反应中实现出色的β选择性。该方法可广泛应用于各种糖基底物,无论其结构和羟基保护功能如何。碳水化合物化学中这种低浓度的1,2-反式β-选择性糖基化消除了使用高反应性硫糖苷构建1,2-反式的限制β糖苷键。这有利于寡糖合成新策略的设计,如生物学相关的β-(1→6)-葡聚糖三糖,β-连接的Gb 3和isoGb 3衍生物的制备所示。

    Concise synthesis of a tetra- and a trisaccharide related to the repeating unit of the O-antigen from Providencia rustigianii O34 is reported. Synthesis of the target oligosaccharides was achieved by rational protecting group manipulations on the commercially available monosaccharides followed by stereoselective glycosylations, using H2SO4-silica for trichloroacetimidate activation and in conjunction

    α‐l‐fucose moieties directly to the secondary rim of βcyclodextrin. Using NMR and MS fragmentation studies, the nonasaccharide structure was determined, which was also visualized using molecular dynamics simulations. The reported glycosylation method proved to be robust on gram‐scale, and may be generally applied to directly glycosylate βcyclodextrins to make well‐defined multivalent glycoclusters.
