  • The effects of solvent on switchable stereoselectivity: copper-catalyzed asymmetric conjugate additions using D2-symmetric biphenyl phosphoramidite ligands
    作者:Han Yu、Fang Xie、Zhenni Ma、Yangang Liu、Wanbin Zhang
    DOI:10.1039/c2ob25730k
    日期:——
    A highly enantioselective copper-catalyzed conjugate addition of diethylzinc to acyclic aromatic enones was developed with phosphoramidite ligands bearing a D2-symmetric biphenyl backbone. This type of reaction demonstrated that toluene and THF solvents can completely reverse the absolute configuration of the products, thus simplifying the process of accessing either enantiomer (S: 92% ee, 94% yield;

    An enantioselective Cu(II)-catalyzed conjugate addition of dialkylzinc reagents to α,β- or α,β,γ,δ-unsaturated ketones with chiral cyclohexane-based amidophosphine ligands was developed. With 2 mol% of Cu(OAc)2·H2O/L5, the conjugate addition of diethylzinc to α,β-unsaturated ketones was achieved in good-to-excellent yields (up to 98%) and high enantioselectivities (up to 92% ee).

    日期:2001.9
    The effectiveness of N,N-dimethyl-2-amino-1,2-diphenylethanol as a chiral ligand was significantly improved via simple hydrogenation of the phenyl rings. Both the catalytic activity and the enantioselectivity of the resulting new ligand in the asymmetric conjugate addition of diethylzinc to enones were found to be superior to the original phenyl analog.
