An efficient synthesis of indeno[1,2-b]quinoline-9,11(6H,10H)-dione derivatives was reported via four-component coupling reaction of aldehydes, dimedone, 1,3-indandione, and amines in refluxing ethanol or three-component condensation of aldehydes, 1,3-indandione, and 5,5-dimethyl-3-arylamino-cyclohex-2-enone derivatives at 120 °C under solvent-free conditions in the presence of a catalytic amount of
通过醛、二甲酮、1,3-茚二酮和胺在回流乙醇中的四组分偶联反应,报道了一种有效合成茚并[1,2-b]喹啉-9,11(6H,10H)-二酮衍生物。醛、1,3-茚二酮和 5,5-二甲基-3-芳氨基-环己-2-烯酮衍生物在无溶剂条件下,在催化量的 Preyssler-type 存在下,在 120 °C 下的三组分缩合杂多酸 H14[NaP5W30O110],作为一种绿色且可重复使用的催化剂。
