Catalytic conjugate additions of heteroarenes to β,β-disubstituted enones are reported. Additions of a range of heteroarene nucleophiles, including furans, indoles, a pyrrole, and a thiophene, to a variety of β,β-disubstituted enones occur to form the corresponding ketone products containing heteroarylated, all-carbon quaternary centers in up to 90% yield. These reactions occur under mild reaction conditions in the presence of low loadings of bismuth triflate.
