An efficient tandem reaction of β-enaminoesters and 1,3-diarylpropenes is disclosed. It undergoes oxidative coupling mediated by DDQ, subsequent intermolecular cyclization and dehydro-aromatization catalyzed by Cu/TBHP in the presence of O2. A series of multi-arylated pyridines is obtained in moderate to excellent yields.
