A series of new boron-containing quinazolinones, benzo[d][1,3,2] diazaborinin-4(1H)-one derivatives, were synthesized by the sequential one-pot reaction of isatoic anhydride, amines, and arylboronic acids in the absence of a catalyst and solvent. Heating isotoic anhydride and amines led to the formation of 2-aminobenzamide intermediates, which reacted easily with boronic acids to obtain the title compounds in good yields. Solvent-free conditions provided a unique procedure because the corresponding products were not obtained using various solvents either under reflux conditions or at room temperature.
