    glycosylating agents. The synthesis is achieved by a C1-to-C5 switch strategy relying on radical decarboxylative fluorination of uronic acids arising from readily available allyl d-C-glycosides. To further showcase the application of this protocol, a structurally unique hexasaccharide composed of →3)-β-d-6didoHepp-(1→4)-β-d-GlcpNAc-(1→ units, corresponding to the capsular polysaccharide of C. jejuni strain
    空肠弯曲杆菌是人类腹泻病的主要原因,已被世界卫生组织指定为高度耐药病原体之一。C. jejuni荚膜多糖具有广泛存在的不常见的 6dHep p残基,并已被证明是开发创新抗菌糖结合疫苗的潜在抗原。为了解决缺乏重要的稀有 6dHep p架构的合成方法,我们在此描述了一种用于制备罕见d -/ l -6dHep p的新颖且有效的方法具有作为糖基化剂的能力的化物。该合成是通过 C1 到 C5 转换策略实现的,该策略依赖于由容易获得的烯丙基d - C-糖苷产生的糖醛酸的自由基脱羧化。为了进一步展示该协议的应用,结构上独特的六糖由 →3)-β- d -6d ido Hep p- (1→4)-β- d -Glc p NAc-(1→ 单位组成,对应于首次组装了空肠弯曲菌 CG8486 菌株的荚膜多糖,该组装的特点是高效构建了具有挑战性的 β-(1,2- cis ) -d- ido-喃庚糖苷通过β-(1
  • Epimerization of 2‘-Carbonylalkyl-<i>C</i>-Glycosides via Enolation, β-Elimination and Intramolecular Cycloaddition

    as an intermediate. When 2'-aldehyde (36) and 2'-ketone (41) of 2,3-di-O-benzyl-alpha/beta-l-C-arabinofuranoside were used as substrates we were able to obtain the respective equatorial alpha-C-arabinopyranosides (37 and 42). These observations confirmed that the epimerization involves an acyclic alpha,beta-unsaturated aldehyde or ketone, which is formed by the enolation of 2'-carbonyl-alpha-C-glycoside
    用4%NaOMe处理葡萄糖,半乳糖甘露糖,2-脱氧和2-叠氮基糖的2'-羰基-α-C-糖喃糖苷导致端基异构体异构化,使其各自的β-端基异构体具有良好或优异的收率。α-C-喃半乳糖苷(10)的2'-醛在氘代甲醇中的差向异构化作用使β-端基异构体在1'-位具有唯一的代取代作用,排除了外糖参与的可能性中间体。当使用2,3-二-O-苄基-α/β-1C-阿拉伯呋喃糖苷的2'-醛(36)和2'-酮(41)作为底物时,我们能够获得各自的赤道α-C-阿拉伯喃糖苷(37和42)。这些观察结果证实,差向异构体涉及无环的α,β-不饱和醛或酮,它是由2'-羰基-α-C-糖苷的烯醇化和随后的β-消除形成的。此后发生分子内杂-迈克尔环加成反应,导致形成热力学控制的稳定产物,该产物仅是赤道的C-糖喃糖苷,但2'-羰基-C-呋喃糖苷除外,其中获得了两种端基异构体的混合物。

  • Ultrasound-assisted synthesis of C-glycosides

    日期:2010.12
    A significant rate enhancement was observed in the preparation of allyl and allenyl-C-glycosides from glycosyl acetate or methyl O-glycoside precursors when ultrasound irradiation was employed as an energy source. The C-glycosides were obtained in 77-96% yields in <20 min using TMSOTf as promoter. These results show that sonication provides rapid and efficient access to useful C-glycoside-based building blocks. (C) 2010 Elsevier Ltd. All rights reserved.
