  • β-Directing Effect of Electron-Withdrawing Groups at <i>O</i>-3, <i>O</i>-4, and <i>O</i>-6 Positions and α-Directing Effect by Remote Participation of 3-<i>O</i>-Acyl and 6-<i>O</i>-Acetyl Groups of Donors in Mannopyranosylations

    isolation of a stable bicyclic trichlorooxazine ring resulting from the intramolecular trapping of the anomeric oxocarbenium ion by 3-O-trichloroacetimidoyl group provided evidence for this remote participation. The triflate anion, counteranion of the mannosyl oxocarbenium ion, was essential for the beta-selectivity, and covalent alpha-mannosyl triflates with an electron-withdrawing group at O-3, O-4
    发现在 O-3、O-4 或 O-6 位具有吸电子的邻三氟甲基苯磺酰基、苄基磺酰基、对硝基苯甲酰基、苯甲酰基或乙酰基的各种受体的甘露糖基化被发现是 β 选择性的,除非供体具有 3-O-酰基和 6-O-乙酰基,主要产物为 α-甘露糖苷。3-O-酰基和 6-O-乙酰基的 α 导向作用归因于它们的远程参与,以及由 3-O-三氯乙亚胺酰基对异头氧代碳鎓离子的分子内捕获所产生的稳定双环三氯恶嗪环的分离小组为这种远程参与提供了证据。三氟甲磺酸盐阴离子,甘露糖基氧代碳鎓离子的抗衡阴离子,对β-选择性至关重要,共价α-甘露糖基三氟甲磺酸盐在O-3处具有吸电子基团,O-4或O-6通过低温NMR检测。强吸电子磺酰基在甘露糖基化中表现出更高的β-导向效应,使α-甘露糖基三氟甲磺酸酯比弱吸电子酰基更稳定。因此,我们提出了 β-甘露糖基化的机制和 β 导向效应的起源:吸电子基团将稳定 α-甘露糖基三氟甲磺酸酯中间体,以及
  • Propargyl Glycosides as Stable Glycosyl Donors:  Anomeric Activation and Glycoside Syntheses
    作者:Srinivas Hotha、Sudhir Kashyap
    DOI:10.1021/ja062425c
    日期:2006.8.1
    The advantages of stable glycosyl donors for saccharide coupling are many, and we describe herein the utility of propargyl glycosides for anomeric activation and glycoside synthesis exploiting the alkynophilicity of AuCl3. Various aglycones were reacted with propargyl glycosides, resulting in the formation of an α,β-mixture of glycosides and disaccharides in good yields.

    Generally applicable and stereoselective formation of 1,2-cis-glycopyranosidic linkage remains a long sought after yet unmet goal in carbohydrate chemistry. This work advances a strategy to this challenge via stereoinversion at the anomeric position of 1,2-trans glycosyl ester donors. This SN2 glycosylation is enabled under gold catalysis by an oxazole-based directing group optimally tethered to a
    1,2-顺式-吡喃糖苷键的普遍适用和立体选择性形成仍然是碳水化合物化学中长期追求但尚未实现的目标。这项工作通过在 1,2-反式糖基酯供体的异头位置上的立体倒置推进了应对这一挑战的策略。这种 S N 2 糖基化是在金催化下通过以恶唑为基础的导向基团实现的,该导向基团最佳地束缚在离去基团上,并在温和的催化条件下以大多数优异的产率和良好的选择性实现。该策略也适用于寡糖的合成。
  • β-Rhamnosides from 6-thio mannosides
    作者:Alphert E. Christina、Daan van der Es、Jasper Dinkelaar、Hermen S. Overkleeft、Gijsbert A. van der Marel、Jeroen D. C. Codée
    DOI:10.1039/c2cc17623h
    日期:——
    Upon condensation of 6-thio-6-deoxy-mannosyl donors 1,2-cis products are obtained with a high degree of stereoselectivity. Subsequent reductive removal of the 6-thio functionality gives 1,2-cisrhamnosides. The 1,2-cis-selectivity can be rationalized with a product forming 3H4-oxocarbenium, which is in equilibrium with a bridged sulfonium intermediate.
    当6-硫-6-脱氧甘露糖供体进行缩合时,会高度立体选择性地得到1,2-顺式产物。随后通过还原性移除6-硫功能基团,生成1,2-顺式鼠李糖苷。1,2-顺式选择性可通过生成产物形式的3H4-氧碳鎓离子来合理化,这一离子与桥连的硫鎓中间体处于平衡状态。
