  • The Amide Group in <i>N</i>-Acetylglucosamine Glycosyl Acceptors Affects Glycosylation Outcome
    作者:Liang Liao、France-Isabelle Auzanneau
    DOI:10.1021/jo050707+
    日期:2005.8.1
    Glycosylation of a disaccharide containing N-acetylglucosamine with rhamnosyl and mannosyl trichloracetimidates under triethysilyl triflate catalysis led to the competitive formation of glycosyl imidates. While the rhamnosyl imidate could be rearranged to the thermodynamically favored trisaccharide, the mannosyl analogue was resistant to rearrangement. Glycosylation with perbenzylated thiorhamnosides activated with methyl triflate (MeOTf) gave the trisaccharide as well as the methyl imidate trisaccharide. The less reactive alpha-thioethyl donor led to a higher relative amount of methyl imidate trisaccharide to trisaccharide than the more reactive beta-thioglycoside. When using a more reactive thioethyl fucoside only the trisaccharide was obtained. Interestingly, the acceptor treated with MeOTf gave the N-methyl imidate that could be easily rhamnosylated and subsequently converted to the N-acetamido trisaccharide. This strategy to glycosylate O-4 of N-acetylglucosamine is under further investigation. Alternatively, bis-N-acetylation of the glucosamine prevented the formation of imidates and allowed the efficient synthesis of two Lewis A trisaccharide analogues.
  • Generalizing Glycosylation:  Synthesis of the Blood Group Antigens Le<sup>a</sup>, Le<sup>b</sup>, and Le<sup>x</sup> Using a Standard Set of Reaction Conditions
    作者:Lin Yan、Daniel Kahne
    DOI:10.1021/ja9608555
    日期:1996.1.1
    glycosylation method under one set of reaction conditions. In this paper, we show that the sulfoxide glycosylation method can be used to form all of the glycosidic linkages in the Lewis blood group antigens Lea (1), Leb (2), and Lex (3) stereoselectively under a uniform set of reaction conditions. This work highlights the flexibility of the sulfoxide method and demonstrates its utility for constructing families
    由于任何糖基化方法都没有通用的反应条件,因此世界上只有少数实验室才能制造出具有生物学意义的寡糖。为了让非专业人士也能合成碳水化合物,关键是要有一种糖基化方法,可以在单一条件下在多种情况下发挥作用。由于结构复杂,Lewis 血型抗原引起了许多合成碳水化合物组的注意。尽管它们已被多次合成,但从未在一组反应条件下使用单一糖基化方法制备它们。在本文中,我们表明亚砜糖基化方法可用于形成路易斯血型抗原 Lea (1)、Leb (2)、和 Lex (3) 在一组统一的反应条件下立体选择性地进行。这项工作突出了亚砜方法的灵活性,并证明了其在构建相关族中的效用...
