    金鸡纳生物碱衍生物催化β-酮酯的对映选择性α-羟基化
    摘要:
    在枯基氢过氧化物(CHP)存在下,实现了由铜吡啶催化的β-酮酯的高效α-羟基化。该反应适用于多种 β-酮酯,以高产率(高达 95%)得到具有优异对映选择性(高达 97% ee)的产物。该反应已成功放大到克级,并且 (S)-5-chloro-2-hydroxy-1-oxo-2,3-dihydro-1H-indene-2-carboxylate – 茚虫威的重要中间体在96% 收率和 86% ee。通过结晶可将对映体过量提高到99%,该方法具有对映选择性高、催化剂易于制备和催化剂回收等优点,具有工业应用前景。

  • Enantioselective organocatalyzed Henry reaction with fluoromethyl ketones
    作者:Marco Bandini、Riccardo Sinisi、Achille Umani-Ronchi
    DOI:10.1039/b807640e
    日期:——
    Remarkable generality in scope of new C9-benzoylcupreines bearing electron-withdrawing substituents for the nitroaldol condensation with fluoromethyl ketones is presented. Both tri- and difluoromethyl ketones provided excellent levels of stereoinduction (ee 76–99%) under mild reaction conditions and low loading of catalyst (1–5 mol%).
    展示了新型C9-苯甲酰杯芳烃在与甲基酮进行硝基醇缩合反应中具有显著的一般性,其含有电子吸引取代基。在温和的反应条件和低催化剂用量(1-5摩尔%)下,三甲基和二甲基酮均提供了优异的立体诱导平(光学纯度ee 76-99%)。

    A deuteriumlabeling reaction of nitroalkanes in deuterium oxide and the subsequent nitroaldol reaction have been accomplished under basic and organocatalytic conditions to provide the deuteriumlabeled β‐nitroalcohols in high yields and high deuterium contents. β‐Deuterated β‐nitroalcohols could be smoothly obtained from the reaction of nitroalkanes and various electrophiles using the easily‐removal

    We report herein a strategy to afford a multicomponent catalytic enantioselective synthesis of β-substituted isoxazolidin-5-ones via a KMC process promoted by a suited cupreine used as bifunctional organocatalyst. The hydroxamic acid component, with a sterically hindered amide moiety, proved to be key for the successful formation and transformation of the obtained original N-amide isoxazolidin-5-ones
    我们在此报告了一种策略,该策略通过由用作双功能有机催化剂的合适碱促进的 KMC 过程提供 β-取代的异恶唑烷-5-酮的多组分催化对映选择性合成。具有空间位阻酰胺部分的异羟酸组分被证明是获得的原始N-酰胺异恶唑烷-5-酮成功形成和转化的关键。

  • Development of C-6′-modified quinine-derived phase-transfer catalysts and their application in the enantioselective α-hydroxylation of β-dicarbonyl compounds
    作者:Hai Qing、Yakun Wang、Zehao Zheng、Shuai Chen、Qingwei Meng
    DOI:10.1016/j.tetasy.2016.07.006
    日期:2016.10
    We have developed C-6'-modified quinine quaternary ammonium salts as phase transfer catalysts for alpha-hydroxylation of beta-dicarbonyl compounds. The quinine quaternary ammonium salts, which was modified at C-6' and the N atom, had good activity for alpha-hydroxylation of B-dicarbonyl compounds. By using 5 mol % of 6-hydroxyl-N-(4'-fluoro-2'-trifluoromethyl)quinine quaternary ammonium salt as the organocatalyst, cumene hydroperoxide as the oxidant, toluene as the solvent, and 50% K2HPO4 as the aqueous alkali at room, temperature, the yield and enantioselectivity of the alpha-hydroxylation of beta-keto esters were 95% and 88%, respectively. This catalytic system was also applicable for beta-keto amides (92% yield and 76% ee). (C) 2016 Elsevier Ltd. All rights reserved.
