    Direct Generation of Nucleophilic Chiral Palladium Enolate from 1,3-Dicarbonyl Compounds:  Catalytic Enantioselective Michael Reaction with Enones
    摘要:
    Generation of chiral palladium enolates from 1,3-dicarbonyl compounds with the palladium aqua complex and its application to the highly efficient catalytic enantioselective Michael reaction with enones are described. The palladium aqua complexes are likely to supply Brønsted base and Brønsted acid successively during the reaction. The former activates the carbonyl compounds to give chiral palladium enolates, and the latter cooperatively activates enones. Using a catalytic amount (2-10 mol %) of the palladium complexes, the various 1,3-dicarbonyl compounds including diketones and beta-ketoesters were converted to the desired Michael adducts in good yields (69-92%) with excellent enantiomeric excesses (89-99% ee).

  • Asymmetric Lewis Acid Catalysis in Water: α-Amino Acids as Effective Ligands in Aqueous Biphasic Catalytic Michael Additions

    native a-amino acids as chiral ligands in aqueous asymmetric Lewis acid catalysis, employing the C-C bond forming Michael addition as a model reaction. Some insights are provided regarding the details of Yb(OTf)(3)/alpha-amino acid-catalyzed Michael additions in water through new kinetic data as well as studies on how both yield and selectivity are influenced by variations in metal/ligand ratio, pH, temperature
    本文探讨了天然α-氨基酸在水性不对称路易斯酸催化中作为手性配体的潜力,采用 CC 键形成迈克尔加成作为模型反应。通过新的动力学数据以及关于产量和选择性如何受金属/配体比变化影响的研究,提供了关于 Yb(OTf)(3)/α-氨基酸催化迈克尔加成在水中的细节的一些见解, α-氨基酸的 pH、温度和结构,通过这项研究发现,仅需要 5 mol% 路易斯酸的反应条件,提供高达 79% 的对映体过量,并且适用于更广泛的捐赠者和接受者比以前证明的要多。重要的是,还证明了α-氨基酸与镱复合。催化剂可能具有大规模应用的潜力,因为它不仅表现出大的配体加速,而且在水中具有良好的溶解性和稳定性。它可以多次循环使用而不会明显损失活性。结果是与水相容的手性路易斯酸的一个有希望的例子。((C) Wiley-VCH Verlag GmbH & Co.

    [reaction: see text] Palladium complexes (1 and 2) were immobilized in ionic liquids, and their applications to catalytic asymmetric fluorination and Michael reaction of beta-ketoesters were successfully demonstrated. This immobilization enabled the reuse of the catalysts no less than 10 times in fluorination and 5 times in Michael reaction with levels of efficiency comparable to those obtained in

    catalytic enantioselective Michael reaction has been developed using chiral palladium complexes. Various substrates including β-keto esters and 1,3-diketones reacted with α,β-unsaturated carbonyl compounds to give the corresponding Michael adducts in good yield with up to 99% ee, thereby affording chiral quaternary carbon centers. In these reactions, chiral palladium enolates were generated as key intermediates

    Asymmetric Michael reactions of ß-ketoesters with enones were effectively catalyzed by complexes of silver salts and BINAP derivatives in water. The reactions have proved to give Michael adducts in high yields with high enantioselectivities. These reactions are the first example of Lewis acid-catalyzed asymmetric Michael reactions in water.
