## Abstract Silicaโ€supported polyphosphoric acid (PPAโ€SiO~2~) catalyzed efficiently the reaction of anthranilamide with aryl aldehydes or ketones under solventโ€free conditions to afford the corresponding 1,2,3,4โ€tetrahydroโ€4โ€quinazolinone derivatives. This work consistently has the advantages of ex
