  • Selective electrochemical glycosylation by reactivity tuning1
    作者:Robert R. France、Richard G. Compton、Benjamin G. Davis、Antony J. Fairbanks、Neil V. Rees、Jay D. Wadhawan
    DOI:10.1039/b316728c
    日期:——
    Electrochemical glycosylation of a selenoglycoside donor proceeds efficiently in an undivided cell in acetonitrile to yield β-glycosides. Measurement of cyclic voltammograms for a selection of seleno-, thio-, and O-glycosides indicates the dependence of oxidation potential on the anomeric substituent allowing the possibility for the rapid construction of oligosaccharides by selective electrochemical activation utilising variable cell potentials in combination with reactivity tuning of the glycosyl donor. A variety of disaccharides are readily synthesised in high yield, but limitations of the use of selenoglycosides as glycosyl donors for selective glycosylation of thioglycoside acceptors are exposed. The first electrochemical trisaccharide synthesis is described.
    在丙酮腈中,未分割电池内的电化学糖基化过程有效地进行,以硒糖供体生成β-糖苷。通过对一系列硒、硫和氧糖苷的循环伏安图测量,表明氧化电位依赖于异头取代基,从而可以通过选择性电化学活化,利用可变电池电位结合糖基供体反应性调节,快速构建寡糖。多种二糖可轻松合成,产率较高,但使用硒糖苷作为糖基供体,在选择性糖基化硫糖苷受体方面存在局限性。首次报道了电化学三糖合成。

    compatible with the hypothesis of a heterolytic cleavage of a CN bond. An early transition state is evidenced by the absence of torsional strain by an annulated 1,3-dioxane ring. Thermolysis of 1 in MeCN at 23° led mostly to the diasteroisomeric (Z,Z)-, (E,E)-, and (E,Z)-lactone azines 56, 57, and 58 (Scheme 6), which convert to 56 under mild conditions, and to 59 (3%). The benzyloxyglucal 59 was obtained

  • Zinc triflate–benzoyl bromide: a versatile reagent for the conversion of ether into benzoate protecting groups and ether glycosides into glycosyl bromides
    作者:Tülay Polat、Robert J. Linhardt
    DOI:10.1016/s0008-6215(02)00481-0
    日期:2003.2
    A simple and efficient method is developed for the chemoselective one-pot conversion of ethers (benzyl, TBDMS and acetal) to the corresponding benzoates by zinc triflate-catalyzed deprotection and benzoylation by benzoyl bromide. In the same reaction, methyl or p-methoxyphenyl glycosides are converted into glycosyl bromides that are useful in glycosylation reactions.
    通过三氟甲磺酸锌催化的脱保护和苯甲酰溴的苯甲酰化,开发了一种简单有效的方法,将醚(苄基,TBDMS和乙缩醛)化学选择性地一锅转化为相应的苯甲酸酯。在同一反应中,甲基或对甲氧基苯基糖苷被转化为可用于糖基化反应的糖基溴化物。
  • Mild Deprotection of Benzyl Ether Protective Groups with Ozone
    作者:Pierre Angibeaud、Jacques Defaye、Andrée Gadelle、Jean-Pierre Utille
    DOI:10.1055/s-1985-31447
    日期:——
    Benzyl ether protective groups are oxidatively removed by ozone under relatively mild conditions. Reaction products are benzoic ester, benzoic acid, and the corresponding alcohol. Subsequent deacylation with sodium methoxide affords a convenient debenzylation technique which has been applied to various O-benzyl protected carbohydrates 1 to afford the deprotected species 2. Glycosides and acetals are unaffected by the treatment.
    苄醚保护基在相对温和的条件下可通过臭氧进行氧化性去除。反应产物为苯甲酸酯、苯甲酸和相应的醇。随后用甲醇钠进行脱酰反应,提供了一种便捷的去苄基化技术,该技术已应用于各种O-苄基保护的碳水化合物1,得到去保护的物种2。糖苷和缩醛不受此处理影响。

    作者:Wei-Yu Shi、Ya-Nan Ding、Nian Zheng、Xue-Ya Gou、Zhe Zhang、Xi Chen、Yu-Yong Luan、Zhi-Jie Niu、Yong-Min Liang
    DOI:10.1039/d1cc03589d
    日期:——
    C-Aryl glycosides are of high value as drug candidates. Here a novel and cost-effective nickel catalyzed ortho-CAr–H glycosylation reaction with high regioselectivity and excellent α-selectivity is described. This method shows great functional group compatibility with various glycosides, showing its synthetic potential. Mechanistic studies indicate that C–H activation could be the rate-determining
