A chemoselective reaction of 2-aminobenzohydrazides and 2-formylbenzoic acid is described for the synthesis of 5H-phthalazino[1,2-b]quinazoline and isoindolo[2,1-a]quinazolinederivatives in ionic liquids catalyzed by iodine. It is found that the type of the products depends on the steric effect in the reactant of 2-aminobenzohydrazides.

A combinatorial synthesis of 3-arylideneaminoquinazolin-4(1H)-one derivatives is described by a reaction of 2-aminobenzohydrazides with two equivalents of aldehydes or ketones in ionicliquidscatalyzed by iodine. Controlling the reaction temperature or reducing the activity of the substrates, respectively, the intermediate products of hydrazones were obtained first, and then they were applied to react
