The prepared new nanopolymer-based composite has been investigated successfully to obtain some 2,3’-dihydroquinazolin-4-(1H)-ones via the reaction of 2-aminobenzamide and various kinds of aldehydes/ cyclic ketones in refluxing ethanol. Short reaction times, the low amount of catalyst, high yields of products, utilizing a wide-range of aldehydes/ ketones, easy work-up procedure, in addition to the accelerating effect of the newly synthesized biodegradable nano composite, are some highlighted features of the reported protocol.}, number={1}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Heidari, Hannaneh and Nikoofar, Kobra and Shahedi, Yeganeh}, year={2024}, month={Feb.}, keywords={Heterogeneous catalyst, Nanofibrillated cellulose, Titanium chloride, 3’-Dihydroquinazolin-4-(1H)-ones} }
