  • Selective deprotection of terminal isopropylidene acetals and trityl ethers using HClO4 supported on silica gel
    作者:Aditi Agarwal、Yashwant D. Vankar
    DOI:10.1016/j.carres.2005.04.005
    日期:2005.7
    Terminal isopropylidene acetals are selectively cleaved to the corresponding 1,2-diols in good to excellent yields in 6-24 h at room temperature by using the 'HClO4.SiO2' reagent system. Likewise, trityl ethers are readily cleaved to the corresponding alcohols in good to excellent yields within 2-3 h at room temperature. Work-up involves merely filtration of the reagent followed by purification of
    通过使用'HClO4.SiO2'试剂系统,在室温下于6-24小时内将末端异亚丙基缩醛以良好至极好的收率选择性裂解为相应的1,2-二醇。同样,在室温下2-3小时内,三甲基醚很容易以良好或优异的收率裂解成相应的醇。后处理仅涉及试剂的过滤,然后纯化粗产物。
  • Copper-Catalyzed Anomeric O-Arylation of Carbohydrate Derivatives at Room Temperature

    日期:2019.7.19
    Direct and practical anomeric O-arylation of sugar lactols with substituted arylboronic acids has been established. Using copper catalysis at room temperature under an air atmosphere, the protocol proved to be general, and a variety of aryl O-glycosides have been prepared in good to excellent yields. Furthermore, this approach was extended successfully to unprotected carbohydrates, including α-mannose
    已经建立了糖乳醇与取代的芳基硼酸的直接和实用的异头O-芳基化。在室温,空气气氛下使用催化,证明该方案是通用的,并且已经以良好至优异的产率制备了各种芳基O-糖苷。此外,该方法已成功地扩展到未保护的碳水化合物(包括α-甘露糖),并在此证明了碳水化合物硼酸之间的相互作用如何与催化结合以实现选择性的异头O-芳基化。
  • Solvent‐Free Glycosylation from per‐ <i>O</i> ‐Acylated Donors Catalyzed by Methanesulfonic Acid
    作者:Serena Traboni、Emiliano Bedini、Alba Silipo、Giulia Vessella、Alfonso Iadonisi
    DOI:10.1002/ejoc.202101121
    日期:2021.11.8
    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
    已经开发出一种新的糖基化程序,具有极低的成本以及实验和环境优势。它是基于直接激活per-的Ó在不存在任何溶剂的5摩尔%便宜和生态友好的甲磺酸-acetylated(或甲酰化)的糖,在空气下。可以快速获得具有良好 1,2-反式立体选择性的多种产品,包括重要的糖苷和二糖。

    The invention provides carbohydrate based compounds, methods of preparation, and compositions useful for modulating signaling through Toll-like receptors. The methods involve contacting a TLR-expressing cell with a carbohydrate based compound of the invention having a core structure comprising of one or more sugar moieties. The carbohydrate based compounds are useful for inhibiting immune stimulation involving TLR ligands, especially TLR4 and TLR2. The compounds also are suitable for inhibition of inflammatory conditions resulting from infections. The compounds have use in the treatment of inflammation, autoimmunity, allergy, asthma, graft rejection, graft versus host disease, infection, sepsis, cancer, and immunodeficiency.

    Reaction of phenyl-trimethylsilylethers (3) with 1-O-trimethylsilyl-2,3,4,6-tetra-O-acetyl-D-glucoside (1) (anomeric mixture) yields almost exclusively the aryl-β-glucosides (4) in the presence of catalytic amounts of TMS-triflate at 20°C, whereas (3) and 1-O-trimethylsilyl-2,3,4,6-tetra-O-benzyl-D-glucoside (2) gives mainly the aryl-α-glucosides (8).
    基三甲基硅烷基醚(3)与1-O-三甲基硅烷基-2,3,4,6-四-O-乙酰基-D-葡萄糖苷(端基混合物)的反应几乎只产生芳基-β-葡萄糖苷(4 )在20°C下催化量的TMS-三氟甲磺酸盐存在下,而(3)和1-O-三甲基硅烷基-2,3,4,6-四-O-苄基-D-葡萄糖苷(2)主要产生芳基-α-葡萄糖苷(8)。
