A new, facile, cost effective, and eco-friendly protocol is reported for the synthesis of 2,3-
dihydroquinazoline-4-(1H)-ones exploring tannic acid as a novel, inexpensive, and
biodegradable catalyst. A variety of dihydroquinazolins were prepared from aromatic aldehydes
and anthranilamide using catalytic amount of tannic acid under solvent free conditions.
Operational simplicity, high yield, and high atom-economy are the important features of this
