4-Aryl and 4-vinyl quinolines were prepared via a sequential procedure involving regioselective Rh(acac)(C2H2)/dppf-catalyzed hydroarylation/hydrovinylation of β-(2-aminophenyl)-α,β-ynones with arylboronic acids or potassium aryl and vinyl trifluoroborates, followed by nucleophilic attack of the amino group onto the carbonyl.
