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 ionic liquids catalyzed 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
通过2-氨基苯甲酰肼与二当量的醛或酮在碘催化的离子液体中的反应,描述了3-芳基氨基喹唑啉-4(1H)-一衍生物的组合合成。分别控制反应温度或降低底物的活性,首先获得的中间产物,然后将它们与各种芳族醛反应而不分离,从而导致喹唑啉酮衍生物的结构多样化。
