A novel approach to construct 2-aryl/heteroaryl quinazolines was developed through iron-catalyzed cascade reaction of 2-aminobenzyl alcohols with benzylamines under aerobic oxidative conditions. The reaction proceeds via the formation of N-benzylidenebenzylamines followed by oxidative trapping of ammonia/intramolecular cyclization in a one-pot manner. The method exhibits a broad substrate scope, high
