    to highly stereoselective synthesis of GalN3-α-O-Ser, which served as the common intermediate for collective synthesis of a wide range of TACAs including TN antigen, STN antigen, 2,6 STF antigen, 2,3 STF antigen, glycophorin and cores 1–8 mucin-type O-glycans. In particular, the rationale for this highly stereoselective α-glycosylation is provided for the first time using DFT calculations and mechanistic
    粘蛋白相关的肿瘤相关碳水化合物抗原(TACA)是癌症疫苗治疗的重要且有趣的靶标。然而,有效获取粘蛋白相关 TACA 库仍然是一项具有挑战性的任务。关键问题之一是 α-GalNAc 连接的构建具有挑战性。在这里,我们报道了用 GalN 3 N-苯基三酰亚胺酯供体进行的高度立体选择性 α-糖基化,其具有优异的产率、出色的立体选择性、广泛的底物范围和温和的反应条件。该方法成功应用于GalN 3 -α- O -Ser的高度立体选择性合成,它作为集体合成各种TACA的通用中间体,包括TN抗原、ST N抗原、2,6 STF抗原、2 ,3 STF 抗原、血型糖蛋白和核心 1-8 粘蛋白型O-聚糖。特别是,首次使用 DFT 计算和机理研究提供了这种高度立体选择性 α-糖基化的基本原理,强调了试剂组合(TMSI 和 Ph 3 PO)的关键作用以及 N 3的氢键导向效应团体。
  • Highly Efficient and Mild Method for Regioselective De-<i>O</i>-benzylation of Saccharides by Co<sub>2</sub>(CO)<sub>8</sub>-Et<sub>3</sub>SiH−CO Reagent System
    作者:Zhao-Jun Yin、Bo Wang、Yang-Bing Li、Xiang-Bao Meng、Zhong-Jun Li
    DOI:10.1021/ol902717y
    日期:2010.2.5
    A highly efficient and mild method for the de-O-benzylation of protected saccharides was developed by transforming terminal benzyl ethers into silyl ethers using Co-2(CO)(8)-Et3SiH under 1 atm of CO. The method was successfully used for the de-O-benzylation of perbenzylated monosaccharides with various anomeric protecting groups, as well as natural disaccharides and trisaccharides such as sucrose, raffinose, and melezitose in good yields (>80%).
  • Glycosylations of Cyclopropyl-Modified Carbohydrates: Remarkable β-Selectivity Using a Mannose Building Block
    作者:Christian Brand、Katharina Kettelhoit、Daniel B. Werz
    DOI:10.1021/ol3024133
    日期:2012.10.5
    A mannosyl donor bearing a spiroannulated cyclopropane unit at C-5 has been prepared, and its behavior in glycosylation reactions investigated. Selectivities in favor of the beta-anomer were observed. Corresponding di- and trisaccharides incorporating the rigid cyclopropane motif were assembled.
