Abstract An efficient and green approach has been developed for the synthesis of 2-substituted 2,3-dihydroquinazolin-4(1H)-ones directly from corresponding substituted aromatic and aliphatic aldehyde and anthranilamide using recyclable polymer supported sulfonic acid catalyst under aqueous conditions. Environmental acceptability, operational simplicity, low cost, excellent functional group compatibility, and high yields are the important features of this protocol.
