  • Copper-mediated O-arylation of lactols with aryl boronic acids
    作者:Jing-Jing Sui、De-Cai Xiong、Xin-Shan Ye

    日期:2019.8
    Abstract An efficient and novel methodology to access phenolic glycosides has been established by using copper-mediated coupling reaction of aryl boronic acids with hemiacetals. The reaction takes place normally in the presence of Cu(OAc)2 (1.0 equiv.) and pyridine (2.0 equiv.) at 40 °C. This protocol distinguishes itself by wide substrate scope, operational simplicity and giving rise to a myriad of

    A novel glycosylation procedure has been developed, featuring extremely low cost as well as experimental and environmental advantages. It is based on the direct activation of per-O-acetylated (or benzoylated) sugars by 5 mol % of cheap and eco-friendly methanesulfonic acid, under air in the absence of any solvent. Several products, including non-trivial glycosides and disaccharides, can be quickly

    The invention relates to a method for labeling specifically living bacteria of a given category of Gram negative bacteria in a sample comprising bacteria, the method comprising the steps of: a) incubating said bacteria of said sample with at least one modified monosaccharide compound comprising a first reactive chemical group capable to react with a second reactive group, so that a monosaccharide residue bearing said first reactive group is incorporated into the polysaccharides of the outer membrane of such bacteria, and b) contacting said modified monosaccharide residue incorporated within the outer membrane of the bacteria, with a labeling molecule comprising a said second reactive group. The said modified monosaccharide compound is a compound having the following formula (I), or a salt thereof: Wherein X can be O, NH or S, R1, R2 and R3 can be independently H, OH, NH2, OH and NH2 being substituted or not by protecting groups thereof, and R4 is H or an alkyl chain in C1 to C4 and at least one of X, R1, R2, R3 and R4 groups being substituted by a said first reactive group R'1.
