AbstractTransition metals-CNT nanocomposites revealed high catalytic activity as a novel and reusable promoting nanocatalyst in the synthesis of quinazolinone heterocyclic compounds. The eco-friendly synthesis was carried out by reacting 2-aminobenzamide (anthranilamide) and various substituted aldehydes without any solvent in the presence of a small amount of the nanocatalyst. These nanocomposites are found to be actual active for the synthesis of 2-aryl-2,3-dihydroquinazolin-4(1H)-ones under solvent free conditions. The use of heterogeneous acid catalyst makes this method quite simple, more convenient, green, and practical. This method presents a significant technique toward an environmentally synthesis of 2-aryl-2,3-dihydroquinazolin-4(1H)-ones.
