    Indium triflate catalyzed peracetylation of carbohydrates
    摘要:
    Peracetylation is a very common protection strategy that is widely implemented in carbohydrate synthesis. Here, a method for the peracetylation of carbohydrates using catalytic In(OTt)(3) in neat acetic anhydride is reported. In(OTf)(3) has low toxicity and is mild and water tolerant, and the reactions are high yielding and efficient. Details regarding the scope and mechanism of the reaction are briefly discussed.

  • Synthesis of Complex Oligosaccharides by Using a Mutated (1,3)--D-Glucan Endohydrolase from Barley
    作者:Jon K. Fairweather、Maria Hrmova、Simon J. Rutten、Geoffrey B. Fincher、Hugues Driguez
    DOI:10.1002/chem.200304733
    日期:2003.6.6
    Complex oligosaccharides with newly formed (1,3)-beta-glycosidic linkages were obtained in good to excellent yields when substituted or unsubstituted alpha-laminaribiosyl fluorides, acting as donors, were condensed onto mono- and disaccharide beta-D-hexopyranoside acceptors by using a (1,3)-beta-D-glycosynthase. These linear and branched (1,3)-beta-linked oligosaccharides could prove to be important
    当取代或未取代的α-laminaribiosyl化物,作为供体,通过缩合生成单糖和二糖β-D-己基喃糖苷受体时,可以良好的产率获得具有新形成的(1,3)-β-糖苷键的复杂寡糖。 (1,3)-β-D-糖基合成酶。这些线性和分支的(1,3)-β-连接的寡糖在医疗,制药和农业应用领域中可能被证明是重要的。此外,观察到(1,3)-β-D-葡聚糖葡糖合酶在其受体亚位点中容纳了(1,3)-,(1,4),-和(1,6)-β-寡糖,但来自高等植物的野生型(1,3)-β-D-葡聚糖内切酶的生理作用却出乎意料。
