Abstrakt: Various di- and mono-substituted quinazolinones were synthesized by one-pot condensation of isatoic anhydride, aldehyde and amine, or ammonium carbonate using [bmim]HSO4 as catalyst in aqueous medium. Water as a reaction media, recyclability of catalyst, shorter reaction time, and good yields (70-90%) are some of the salient features of the developed protocol. [ABSTRACT FROM AUTHOR]
