Sodium tetraarylborates as effective nucleophiles in rhodium/diene- catalyzed 1,4-addition to β,β-disubstituted α,β-unsaturated ketones: Catalytic asymmetric construction of quaternary carbon stereocenters

Article abstract of DOI:10.1021/ja905432x

(Chemical Equation Presented) A rhodium-catalyzed 1,4-addition of sodium tetraarylborates to β,β-disubstituted α,β-unsaturated ketones is described. Highly efficient asymmetric catalysis has also been achieved by employing a readily available chiral diene
