A rhodium-catalyzed1,4-addition of sodium tetraarylborates to β,β-disubstitutedα,β-unsaturated esters has been developed. Highly efficient asymmetric catalysis has also been described to create quaternary carbon stereocenters at the β-position of esters by tuning the ester group of substrates and employing a readily available chiral diene ligand.
