Palladium[0]-mediated Ullmann cross-coupling of 1-bromo-2-nitrobenzene (1 R = H) and its derivatives with a range of beta-halo-enals, -enones, or -esters readily affords the corresponding beta-aryl derivatives, which are converted into the corresponding quinolines, 2-quinolones, phenanthridines, or 6(5H)-phenanthridinones on reaction with
New protocols for the synthesis of 3, 4-annulated and 4-substituted quinolines from ?-bromo-a, ?-unsaturated aldehydes and 1-bromo-2-nitrobenzene or 2-bromoacetanilide.
