    用硫代亚氨酸糖基供体催化糖基化
    摘要:
    一类新的糖基硫代亚氨酸盐,即糖基 N-苯基-三氟硫代乙亚胺酸盐,是从容易获得的糖基硫醇以优异的产率制备的。这些亚胺酯在催化量的BF3·Et2O的作用下表现出非常好的供体性质,并且相应的糖苷化产物以非常好的收率形成。因此,实现了与糖基硫代亚氨酸酯供体的第一次催化糖基化。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)

  • Methyl 1,2-Orthoesters as Useful Glycosyl Donors in Glycosylation Reactions: A Comparison with n-Pent-4-enyl 1,2-Orthoesters
    作者:Clara Uriel、Juan Ventura、Ana M. Gómez、J. Cristóbal López、Bert Fraser-Reid
    DOI:10.1002/ejoc.201200089
    日期:2012.6
    Mannopyranose-derived methyl 1,2-orthoacetates (R = Me) and -benzoates (R = Ph) can function as glycosyl donors – upon BF3·Et2O activation in CH2Cl2 – in glycosylation reactions with monosaccharide acceptors to afford disaccharides in good yields. In the process, glycosylation is preferred to acid-catalyzed rearrangement leading to methyl mannopyranosides. Methyl 1,2-orthoesters can be also used in regioselective
    甘露糖衍生的 1,2- 原乙酸甲酯 (R = Me) 和 -苯甲酸酯 (R = Ph) 可以作为糖基供体 - 在 CH2Cl2BF3·Et2O 活化后 - 在与单糖受体的糖基化反应中以良好的收率提供二糖。在该过程中,糖基化优于酸催化重排,导致甲基甘露糖苷。甲基 1,2-原酸酯也可用于单糖二醇的区域选择性糖基化方案,其中它们显示出良好的区域选择性。

  • Forced Complexation of Nitrogen Leading to a Weakening of Amide Bonds: Application to a New Linker for Solid-Phase Chemistry

    subsequently can be cleaved under very mild conditions by methanolysis. On the basis of this principle we developed a versatile and robust linker for solid-phase chemistry. The stability of the linker was demonstrated under acidic and basic conditions, and it was evaluated for its utility in peptide synthesis as well as for reductive amination, Pd-mediated C–C-coupling, and metathesis reactions.(© Wiley-VCH

  • Chelating Carboxylic Acid Amides as Robust Relay Protecting Groups of Carboxylic Acids and their Cleavage under Mild Conditions
    作者:Manuel C. Bröhmer、Stephan Mundinger、Stefan Bräse、Willi Bannwarth
    DOI:10.1002/anie.201100271
    日期:2011.6.27
    Free choice: Carboxamides of bispicolylamine are alternative protecting groups for carboxylic acids (see scheme). As a consequence of their straightforward applicability, their high chemical stability towards a broad range of conditions, and their selective cleavage under mild conditions to give either carboxylic acids or their methyl esters, this new protection method should find widespread application
