  • Modified One‐Pot Protocol for the Preparation of Thioglycosides from Unprotected Aldoses via <i>S</i>‐Glycosyl Isothiouronium Salts
    作者:Pallavi Tiwari、Geetanjali Agnihotri、Anup Kumar Misra
    DOI:10.1080/07328300500256775
    日期:2005.9.1
    An efficient onepot protocol for the direct preparation of thioglycosides starting from unprotected reducing sugars via S‐glycosyl isothiouronium salts is reported. In this onepot methodology, BF3 · OEt2 has been used as a general catalyst for both per‐O‐acetylation of sugars and conversion of sugar per‐O‐acetates into S‐glycosyl isothiouronium salts, which was allowed to react with alkylating agents
    据报道,一种有效的一锅法方案可直接从未保护的还原糖开始,通过S-糖基异硫脲盐直接制备糖苷。在这种一锅法中,BF3·OEt2已被用作糖的全O-乙酰化和糖的过O-乙酸转化为S-糖基异硫脲盐的通用催化剂,该盐可与烷化剂反应在碱的存在下以优异的产率提供代糖苷。* CDRI通讯号 6767.作者对这项工作做出了同等的贡献。

    d-Glucose, d-galactose, d-mannose, d-xylose, l-arabinose, l-fucose, l-rhamnose, maltose, cellobiose, lactose, d-glucosamine, d-galactosamine, and d-mannosamine were converted into the corresponding methyl per-O-acetyl 1-thioglycopyranosides by way of a three-step (acetobromination, methylthioation, and acetylation) through-process in a single vessel.
    d-葡萄糖、d-半乳糖、d-甘露糖、d-木糖、l-阿拉伯糖、l-岩藻糖、l-鼠李糖麦芽糖纤维二糖乳糖、d-葡萄糖胺、d-半乳糖胺和d-甘露糖胺通过一个反应器经过三步(乙酰化、甲化和乙酰化)转化为相应的甲基全乙酰化1-代糖呋喃糖苷。

  • Streamlined Synthesis of Per-<i>O</i>-acetylated Sugars, Glycosyl Iodides, or Thioglycosides from Unprotected Reducing Sugars<sup>1</sup>
    作者:Balaram Mukhopadhyay、K. P. Ravindranathan Kartha、David A. Russell、Robert A. Field
    DOI:10.1021/jo048890e
    日期:2004.10.1
    Solvent-free per-O-acetylation of sugars with stoichiometric acetic anhydride and catalytic iodine proceeds in high yield (90-99%) to give exclusively pyranose products as anomeric mixtures. Without workup, subsequent anomeric substitution employing iodine in the presence of hexamethyldisilane (i.e., TMS-I generated in situ) gives the corresponding glycosyl iodides in 75-95% isolated yield. Alternatively, and without workup, further treatment with dimethyl disulfide or thiol (ethanethiol or thiocresol) gives anomerically pure thioglycosides in more than 75% overall yield.
