Fe3O4-TDSN-Bi(III) was utilized as an efficient and reusable catalyst for the regioselective one-pot synthesis of quinoline derivatives from arylamines, arylaldehydes and methyl propiolate under microwave irradiation and solvent-free conditions. Also, bis-quinolines were obtained in high yields from dialdehydes or diamines. Atom-economy, high to excellent yields, easy work-up, as well as simple catalyst
Fe 3 O 4 -TDSN-Bi(III)被用作有效和可重复使用的催化剂,用于在微波辐射和无溶剂条件下从芳基胺,芳基醛和丙炔酸甲酯区域选择性地一锅合成喹啉衍生物。同样,从二醛或二胺以高收率获得双喹啉。原子经济,高至优异的收率,易于后处理以及简单的催化剂回收和可重复使用性是此程序的关键特征。
