NLRP3inflammasome is an important therapeutic target for a number of human diseases. Herein, computationally designed series of quinazolin-4(3H)-ones were synthesized using iodine-catalyzed coupling of arylalkynes (or styrenes) with O-aminobenzamides. The key event in this transformation involves the oxidative cleavage of the C–C triple/double bond and the release of formaldehyde. The reaction relies

and environmentally benign method for the one-pot cascade synthesis of quinazolin-4(3H)-ones via acceptorless dehydrogenative coupling of o-aminobenzamide with alcohols catalyzed by a simple Ni(II) catalyst, [Ni(MeTAA)], featuring a tetraaza macrocyclic ligand (tetramethyltetraaza[14]annulene (MeTAA)). A wide variety of substitutedquinazolin-4(3H)-ones were synthesized in high yields starting from
