  • Direct Dehydrative Pyridylthio-Glycosidation of Unprotected Sugars in Aqueous Media Using 2-Chloro-1,3-dimethylimidazolinium Chloride as a Condensing Agent

    enzyme inhibitors in sugar chemistry, have been synthesized directly from the corresponding unprotected sugars in good yields by using 2‐chloro‐1,3‐dimethylimidazolinium chloride (DMC) as dehydrative condensing agent. The reaction proceeds in aqueous media without using any protecting groups, affording 2‐pyridyl 1‐thioglycosides with β‐configuration selectively. According to the present method, not
    通过使用2--1,3-二甲基咪唑啉化物(DMC)作为脱缩合剂,可以直接从相应的未保护糖以高收率直接合成各种2-吡啶基1-代糖苷,糖化学中的重要合成中间体和酶抑制剂。反应在性介质中进行,无需使用任何保护基,选择性地提供具有β-构型的2-吡啶基1-代糖苷。根据本方法,不仅未保护的单糖,而且未保护的寡糖,例如纤维寡糖,壳寡糖,麦芽寡糖氨基葡萄糖低聚物,都可以转化为相应的2-吡啶基衍生物,这将大大扩展芳基1-代糖苷在糖化学中的应用。
  • Thermotropic Liquid Crystals Based on Chito-Oligosaccharides. 1. Synthesis of Chitobiose Octaalkanoates and Chitotriose Undecaalkanoates and Their Thermal Properties
    作者:Makoto Sugiura、Masahiko Minoda、Junji Watanabe、Takeshi Fukuda、Takeaki Miyamoto
    DOI:10.1246/bcsj.65.1939
    日期:1992.7
    This paper deals with the preparation of two series of chito-oligosaccharide derivatives, chitobiose octaalkanoates, and chitotriose undecaalkanoates, in which the amino- and hydroxyl groups were blocked with alkyl pendants of differing lengths via an ester linkage. By differential scanning calorimetry(DSC) and optical microscopic observations, these compounds were found to exhibit an enantiotropic mesophase at temperatures ranging from ca. 50 °C to ca. 200 °C. The texture of the mesophases were similar to those of the discotic columnar liquid crystals formed by the cellobiose and cellotriose equivalents. However, the amido group in the chito-derivatives seems to stabilize the mesophase to an appreciable extent, bringing about higher temperatures and a longer temperature span of the mesophase than those of the cello-equivalents.
