AbstractAn efficient, useful and general procedure for the synthesis of 2,4-disubstituted quinolines via one-pot three-component reaction of aryl amines, aryl aldehydes and phenylacetylene using Al2O3 nanoparticles/methanesulfonic acid (nano-AMA) as a new catalyst has been described. The major advantages of this protocol are high yields, inexpensive catalyst, short reaction times, green and reusable
摘要通过使用Al 2 O 3纳米颗粒/甲磺酸(nano-AMA)作为新化合物,通过芳基胺,芳基醛和苯乙炔的一锅三组分反应,合成2,4-二取代喹啉的有效,有用和通用程序已经描述了催化剂。该方案的主要优点是高产率,廉价的催化剂,较短的反应时间,绿色和可重复使用的非均相纳米催化剂。发现该催化剂是可回收的,并且可以使用多达五次而不会显着降低其活性。 图形概要
