  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.

  The Pd-catalyzed hydroarylation of beta-(2-aminoaryl)-alpha,beta-ynones with organoboron derivatives, leading to 2,4-diarylquinolines in good to excellent yields through sequential cycloamination, has been investigated. The reaction is catalyzed by both Pd(II) and Pd(0) precatalysts, and can be carried out even under neutral conditions. The regiochemical outcome is inverted with respect to the Pd-catalyzed hydroarylation of beta-(2-aminoaryl)-alpha,beta-ynones with aryl iodides. This aspect has been rationalized using quantum-chemical calculations, which show significant differences between the energy barriers of the regioisomeric transition states for the migratory insertion (hydropalladation) step, and are consistent with the charge density of the pi complex that undergoes such insertion.
