Enantioselective conjugate hydrosilylation of β,β-disubstituted α,β-unsaturatedketones was realized. In the presence of a chiral picolinamide–sulfonate Lewis base catalyst, the reactions provided various chiral ketones bearing a chiral center at the β-position in up to quantitative yields with moderate enantioselectivities.
