Asymmetric beta-boration of alpha,beta-unsaturated carbonyl compounds promoted by chiral rhodium-bisoxazolinylphenyl catalysts.
Chiral rhodium-bisoxazolinylphenyl acetate complexes exhibited high catalytic activity for the beta-boration of alpha,beta-unsaturated carbonyl compounds with bis(pinacolato)diboron in the presence of sodium t-butoxide with enantioselectivity up to 97%.
