    Facile Preparation and Utilization of a Novelβ-D-ManNAcA-Donor: Methyl 2-Benzoyloxyimino-1-bromo-2-deoxy-α-D-arabino-hexopyranuronate
    摘要:
    标题为β-d-ManNAcA供体的化合物,甲基2-苯甲氧基亚胺-2-脱氧-d-阿拉伯六糖糖醛酸α-溴化物9,已从d-葡萄糖醛内酯合成,七个步骤的总体产率为21%,所有中间体均能以晶体形式获得。关键化合物是2-乙酰氧基-d-葡萄糖醛酯6及其羟胺水解产物1,5-脱水-d-果糖醛酸肟7,后者通过O-苯甲酰化(→8)和光溴化进一步合成9。——作为合适的β-d-ManNAcA供体,9的利用基于两个后续反应:首先,以N封闭的2-氨基乙醇作为间隔底物,或以其他保护的糖苷的6-羟基(16)进行Koenigs-Knorr型糖苷化反应,产生β选择性达到20:1或更高;其次,通过对获得的β-糖苷进行肟还原,基本上以立体专一性的方式进行,经过N-乙酰化后,得到2-乙酰氨基-2-脱氧-β-d-甘露糖醛酸酯。——所开发的方法用于制备一些新型人工糖脂,例如(肉豆蔻酰氨基)乙基6-O-(2-乙酰氨基-2-脱氧-β-d-甘露糖吡喃糖醛酸)-α-d-葡萄糖吡喃糖苷(25)及其(硬脂酰氨基)乙基类似物(26),这些化合物正被评估作为脂质体的识别标记。

    摘要:
    Practical protocols are described for a five-step conversion Of D-glucuronolactone into Ot-D-arabino-2-ketoglueuronyl bromides, which due to their alpha-selective or beta-specific glycosidation, and gluco- or manno-specific carbonyl reductions of the glucurono2-ulosides formed, are expedient indirect donor substrates for the efficient introduction Of alpha-D-GIcA or beta-D-ManA residues.

  • Extended scaffold glucuronides: <i>en route</i> to the universal synthesis of <i>O</i>-aryl glucuronide prodrugs
    作者:Raoul Walther、Morten T. Jarlstad Olesen、Alexander N. Zelikin

    日期:——
    We demonstrate that an extended scaffold based on a self-immolative linker (SIL) enables the universal production of O-aryl glucuronide prodrugs: high yield glucuronidation is performed on a precursor substrate (SIL) and the subsequent drug conjugation proceeds via less challenging chemical reactions.

    A convenient and efficient method for preparing 2-hydroxy glycals was developed from thioglycosides by using 1,4-dioxane–bromine complex/DMAP as an efficient promoter with good yield (61–85%). In this synthetic method, a wide range of sugar thioglycosides could be used as substrates.

    Polymethylhydrosiloxane (PMHS) proved to be a practically convenient alternative to triethylsilane in a large set of synthetic elaborations entailing the quick generation of glycosyl iodides with a iodine/silane combined reagent. In addition, the scope of this combined reagent was expanded to the especially fast generation of 2-acetoxyglycals, and the rapid synthesis of useful building-blocks of D-glucuronic

  • Synthesis of a 2-Acetamido-2-deoxy-β-D-mannuronic Acid-Containing Artificial Glycolipid Corresponding to the Repeating Unit of a Teichuronic Acid from<i>Micrococcus luteus</i>
    作者:Yumiko Osa、Eisuke Kaji、Keiko Takahashi、Motoko Hirooka、Shonosuke Zen、Frieder W. Lichtenthaler
    DOI:10.1246/cl.1993.1567
    日期:1993.9
    A new type of artificial glycolipid constituted with 2-acetamido-2-deoxy-β-D-mannuronic acid was synthesized utilizing a readily accessible building block, methyl 2-(benzoyloxy)iminoglycosuronate as the glycosyl donor. Stereocontrolled β-glycosidation of the donor was as smoothly effected as the subsequent stereospecific reduction of (benzoyloxy)imino function. After anomeric activation, attachment of the spacer (2-aminoethanol)-linked stearic acid and final deblocking gave the designed glycolipid in good overall yield.

  • A convenient new synthesis of quaternary ammonium glucuronides of drug molecules
    作者:Lisa Iddon、Ryan A. Bragg、John R. Harding、Andrew V. Stachulski
    DOI:10.1016/j.tet.2009.10.113
    日期:2010.1
    N-Glucuronides, of various Structural types, are frequently encountered as drug metabolites. Efficient chemical synthesis of these compounds, both as analytical standards and for toxicological investigation, is therefore an important goal. Earlier syntheses of N+-glucuronides of aliphatic tertiary amine drugs involved direct reaction of the drug molecule with a bromosugar, but yields were generally low and of poor reproducibility, with many by-products. In addition the final products were often of low stability, hindering effective isolation and purification. We now report that a stable, readily prepared glucuronic acid hemiacetal is a reliable precursor for metabolites of this type and give three pharmaceutically relevant examples. We report further on the stability of the final metabolites and the conditions required for their isolation and purification. (C) 2009 Elsevier Ltd. All rights reserved.
