AbstractA facile and efficient procedure has been reported for the synthesis of tetrahydrofuro[3,4-b]quinoline-1,8(3H,4H)-diones by the condensation reaction of benzaldehydes, 1,3-cyclohexanediones and anilinolactones in the presence of CuFe2O4 as a reusable nanocatalyst with high catalytic activity in water. The notable advantages of this method are excellent isolated yields, short reaction times
摘要据报道,通过苯甲醛,1,3-环己烷二酮和苯胺内酯的缩合反应合成四氢呋喃并[3,4- b ]喹啉-1,8(3 H,4 H)-二酮的简便有效的方法。 CuFe 2 O 4作为在水中具有高催化活性的可重复使用的纳米催化剂的存在。该方法的显着优势是优异的分离产率,较短的反应时间,简单的后处理程序以及对环境的影响很小。 图形概要 。
