    Stereoselective Synthesis of Di- and Trisaccharide Fucoidan Fragments Bearing α-D-Glucuronic Acid Residue∗
    摘要:
    The first stereoselective synthesis of disaccharide alpha-D-GlcA-(1 -> 2)-alpha-L-Fuc-OPr ( 1), trisaccharide (1 -> 3)-alpha-L-Fuc-[alpha-D-GlcA-(1 -> 2)]-alpha-L-Fuc-OPr(3), and their selectively O-sulfated derivatives 2 and 4 bearing sulfo-groups at O(4) of the fucose units has been performed. Compounds 1-4 represent the fragments of the chain of the fucoidan from Cladosiphon okamuranus brown seaweed. Glucuronylation by a series of selectively O-acetylated glucuronyl bromides was studied to obtain the target products. It has been found that 3-O-acetylated donor 6 is the most efficient agent for alpha-glycoside bond formation that can be connected with intramolecular remote participation of 3-O-acetyl group favoring alpha-stereoselectivity.

  • Nucleophile-Directed Stereocontrol Over Glycosylations Using Geminal-Difluorinated Nucleophiles
    作者:Benjamin Schumann、Sharavathi G. Parameswarappa、Marilda P. Lisboa、Naresh Kottari、Fabio Guidetti、Claney L. Pereira、Peter H. Seeberger

    close proximity to the hydroxy group of an aliphatic amino alcohol lowers the oxygen nucleophilicity and reverses the stereoselectivity of glycosylations to preferentially form the desired cis‐glycosides with a broad set of substrates. This concept was applied to the design of a cis‐selective linker for automated glycan assembly. Fluorination of an amino alcohol linker does not impair glycan immobilization
    糖基化反应是寡糖合成中的关键转化,但在许多情况下仍然难以控制。顺式-糖苷键形成过程中的立体控制几乎完全依赖于调节糖基化剂或反应条件。在这里,我们使用亲核试剂定向的立体控制来操纵糖基化反应的立体选择性。将两个氟原子紧邻脂肪族氨基醇的羟基放置会降低氧的亲核性,并逆转糖基化的立体选择性,从而优先形成所需的具有多种底物的顺式-糖苷。此概念已应用于顺式设计用于自动聚糖组装的选择性接头。如聚糖微阵列实验所示,氨基醇接头的氟化不会损害聚糖固定化和凝集素结合。这些氟化的连接基使得能够容易地生成α末端的合成聚糖,从而形成糖缀合物。

    A simple and convenient method for the esterification of various monosaccharide and disaccharide uronic acids, derived from glucose, galactose and mannose, was developed with different alcohols using the eco-friendly catalyst silica-sulphuric acid (H2SO4-SiO2). The esterification reactions proceeded at room temperature under mild conditions with excellent yields. Under the standard reaction conditions

    Streptococcus pneumoniae (SP) bacteria cause serious invasive diseases. SP bacteria are covered by a capsular polysaccharide (CPS) that is a virulence factor and the basis for SP polysaccharide and glycoconjugate vaccines. The serotype 9V is part of the currently marketed conjugate vaccine and contains an acetate modification. To better understand the importance of glycan modifications in general and

  • Thioglycuronides:  Synthesis and Application in the Assembly of Acidic Oligosaccharides
    作者:Leendert J. van den Bos、Jeroen D. C. Codée、John C. van der Toorn、Thomas J. Boltje、Jacques H. van Boom、Herman S. Overkleeft、Gijsbert A. van der Marel
    DOI:10.1021/ol049380+
    日期:2004.6.1
    Partially protected thioglycuronic acids are prepared efficiently by chemo- and regioselective oxidation of the corresponding thioglycosides using the TEMPO/BAIB reagent combination. After esterification, the thioglycuronic acids proved to be useful as both donor and acceptor in sulfonium-mediated condensations toward acidic di- and trisaccharides.
