A new series of 1,5-disubstituted pyrrolo[1,2-a]quinazoline derivatives were prepared from 2-chloro-4-substituted quinazolines, propargyl alcohol, and secondary amines through novel multi-component reactions. These one-pot reactions, carried out in the presence of a palladium-copper catalyst, provide an efficient method for the synthesis of functionalized pyrrolo[1,2-a]quinazolines in good-to-high
由2-氯-4-取代的喹唑啉,炔丙醇和仲胺通过新颖的多组分反应制备了一系列新的1,5-二取代的吡咯并[1,2- a ]喹唑啉衍生物。在钯-铜催化剂的存在下进行的这些一锅法反应提供了一种以高到高产率合成官能化吡咯并[1,2- a ]喹唑啉的有效方法。使用良好扩散方法,对许多合成的化合物针对革兰氏阳性和革兰氏阴性细菌的体外抗菌活性进行了筛选。产物的抗氧化活性也用DPPH(2,2-二苯基-2-吡啶基肼基)测定法评估。
