  • Copper-Catalyzed Conjugate Additions of Alkylboranes to Imidazolyl α,β-Unsaturated Ketones: Formal Reductive Conjugate Addition of Terminal Alkenes
    作者:Hirohisa Ohmiya、Mika Yoshida、Masaya Sawamura
    DOI:10.1021/ol102819k
    日期:2011.2.4
    Conjugate addition of alkylboron compounds (alkyl-9-BBN) to imidazol-2-yl α,β-unsaturated ketones proceeded in the presence of a catalytic amount (10 mol %) of CuCl, 1,3-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene (IMes), and t-BuOK. The alkylboranes are available through alkene hydroboration, and thus the overall process represents a reductive conjugate addition of alkenes to enone derivatives. A

  • Asymmetric Catalysis with Substitutionally Labile yet Stereochemically Stable Chiral-at-Metal Iridium(III) Complex
    作者:Haohua Huo、Chen Fu、Klaus Harms、Eric Meggers
    DOI:10.1021/ja4132505
    日期:2014.2.26
    A metal-coordination-based high performance asymmetric catalyst utilizing metal centrochirality as the sole element of chirality is reported. The introduced substitutionally labile chiral-at-metal octahedral iridium(III) complex exclusively bears achiral ligands and effectively catalyzes the enantioselective Friedel-Crafts addition of indoles to α,β-unsaturated 2-acyl imidazoles (19 examples) with
    报道了一种利用属中心手性作为唯一手性元素的基于属配位的高性能不对称催化剂。引入的取代不稳定手性属八面体 (III) 配合物仅带有非手性配体,并以高产率(75%)有效催化吲哚与 α,β-不饱和 2-酰基咪唑(19 个实例)的对映选择性弗里德尔-克拉夫茨加成-99%) 和高对映选择性 (90-98% ee) 在低催化剂负载 (0.25-2 mol %) 下。与直觉相反,尽管其置换不稳定,这是与 2-酰基咪唑底物配位所必需的,但属中心手性在整个催化过程中保持不变。这种新型的活性手性属配合物可能对各种不对称转化具有很高的价值。
  • Enantioselective Friedel−Crafts Alkylations Catalyzed by Bis(oxazolinyl)pyridine−Scandium(III) Triflate Complexes
    作者:David A. Evans、Keith R. Fandrick、Hyun-Ji Song、Karl A. Scheidt、Risheng Xu
    DOI:10.1021/ja072976i
    日期:2007.8.1
    The enantioselective Friedel-Crafts addition of a variety of indoles catalyzed by bis(oxazolinyl)pyridine-scandium(III) triflate complexes (Sc(III)-pybox) was accomplished utilizing a series of beta-substituted alpha,beta-unsaturated phosphonates and alpha,beta-unsaturated 2-acyl imidazoles. The acyl phosphonate products were efficiently transformed into esters and amides, whereas the acyl imidazole adducts were converted to a broader spectrum of functionalities such as esters, amides, carboxylic acids, ketones, and aldehydes. The sense of stereoinduction and level of enantioselectivity were found to be functions of the size of the substrate employed, the substitution on the ligand, and the catalyst loading. Molecular modeling of the catalyst with the bound substrates was performed based on the crystal structures of the catalyst complexes and the sense of stereoinduction observed in the addition reaction. Nonlinear effects over a range of catalyst concentrations implicate a mononuclear complex as the active catalyst.
  • Enantioselective Nitrone Cycloadditions of α,β-Unsaturated 2-Acyl Imidazoles Catalyzed by Bis(oxazolinyl)pyridine−Cerium(IV) Triflate Complexes
    作者:David A. Evans、Hyun-Ji Song、Keith R. Fandrick
    DOI:10.1021/ol061223i
    日期:2006.7.1
    Enantioselective nitrone cycloadditions with, ss-substituted alpha,ss-unsaturated 2-acyl imidazoles catalyzed by bis(oxazolinyl) pyridine-cerium(IV) triflate complexes 1 have been reported. The isoxazolidine products were efficiently transformed into densely functionalized, ss'- hydroxy-ss-amino acid derivatives.
