  • Enantioselective synthesis of coumarins catalyzed by an isosteviol‐derived tertiary amine‐squaramide catalyst
    作者:Zhiwei Ma、Chuanchuan Wang、Xiaofeng Liu、Xiaopei Chen、Jingchao Tao、Quanjian Lv
    DOI:10.1002/chir.23401
    日期:2022.2
    newly tertiary amine-squaramide organocatalyst has been successfully developed and applied into the asymmetric Michael addition of 4-hydroxycoumarin to β,γ-unsaturated α-ketoesters. The catalyst system performed well with a low catalyst loading of 1 mol% under mild reaction conditions. A series of coumarin derivatives were obtained in good to high yields (up to 97%) with high enantioselectivities (up
    一种新的叔胺-方酰胺有机催化剂已成功开发并应用于4-羟香豆素与β,γ-不饱和α-酮酯的不对称迈克尔加成反应。该催化剂体系在温和的反应条件下以 1 mol% 的低催化剂负载量表现良好。以良好至高产率(高达 97%)和高对映选择性(高达 96% ee)获得了一系列香豆素生物
  • Conjugate Addition of Carbon Acids to β,γ-Unsaturated α-Keto Esters: Product Tautomerism and Applications for Asymmetric Synthesis of Benzo[<i>a</i>]phenazin-5-ol Derivatives
    作者:Rinat S. Tukhvatshin、Alexander S. Kucherenko、Yulia V. Nelyubina、Sergei G. Zlotin

    by the asymmetric Michael reactions of cyclic carbon acids with β,γ-unsaturated α-keto esters and the chemical shift of the α-proton in starting nucleophilic substrates was revealed which makes equilibration predictable. New tetrahydropyran-fused benzo[a]phenazins were enantioselectively (up to 99% ee) synthesized from β,γ-unsaturated α-keto esters and benzo[a]phenazin-5-ol, a powerful anti-cancer agent
    揭示了由环状碳酸与β,γ-不饱和α-酮酯的不对称迈克尔反应生成的互变异构产物的平衡比与起始亲核底物中α-质子的化学位移之间的相关性,这使得可预测平衡。由β,γ-不饱和α-酮酯和强效抗癌剂苯并[a]吩嗪-5-醇对映体选择性合成(高达99%ee)对映体,合成了新的四氢吡喃苯并[a]吩嗪。证明了催化剂Ia在催化反应中的易回收性。
  • Azetidine-Derived Dinuclear Zinc-Catalyzed Asymmetric Conjugate Addition of Bioactive Heterocycles to β,γ-Unsaturated α-Keto esters

    A general AzePhenol dinuclear zinc catalytic system has been successfully developed and applied into the asymmetric Michael addition of 4-hydroxyl pyrones and 4-hydroxycoumarins to β,γ-unsaturated α-keto esters. Excellent yields (up to 99%) and high enantioselectivities (up to 94% ee) are obtained for a wide range of substrates under mild conditions in the absence of additives. This bimetallic catalytic
    已成功开发出通用的AzePhenol双核催化体系,并将其应用于将4-羟吡喃酮4-羟香豆素不对称迈克尔加成到β,γ-不饱和α-酮酸酯上。在温和条件下没有添加剂的情况下,对于多种底物,均具有出色的收率(最高99%)和高对映选择性(最高94%ee)。这种双属催化方法代表了一种新的有效的不对称合成方案,可以访问具有药理学意义的多种生物活性化合物。提出了可能的机制来解释不对称感应的起源。
