In this study, we have described a clean and facile condensation reaction of various aromatic aldehydes or cyclic ketones with 2-aminobenzamide under mild conditions in the presence of C–SO3H as an efficient catalyst derived from glycerol. This protocol furnishes an imperative avenue for the access of 2,3-dihydroquinazolin-4(1H)-ones in excellent yields with a range of structural diversity. The recovered catalyst has been engineered for subsequent runs with substantial activity.Graphical Abstract
