A simple and facile synthesis of highly functionalized quinazoline derivatives has been successfully developed by treatment of aldehydes, ammonium acetate, and 2-aminoaryl ketones or isatoic anhydride under reflux conditions in the presence of a pentafluorophenylammonium triflate (PFPAT) organocatalyst. These catalytic condensation reactions represent green chemical processes, while the PFPAT organocatalyst is air-stable, cost-effective, easy to handle, and easily removed from the reaction mixtures.
