  • Title: Sodium tetraarylborates as effective nucleophiles in rhodium/diene-catalyzed 1,4-addition to beta,beta-disubstituted alpha,beta-unsaturated ketones: catalytic asymmetric construction of quaternary carbon stereocenters.

    Abstract:
    A rhodium-catalyzed 1,4-addition of sodium tetraarylborates to beta,beta-disubstituted alpha,beta-unsaturated ketones is described. Highly efficient asymmetric catalysis has also been achieved by employing a readily available chiral diene ligand, leading to the construction of quaternary carbon stereocenters with high enantioselectivity.
