中文摘要：
以芳醛、1，3-茚二酮、烯胺酮为原料，冰醋酸为溶剂，三组分一锅法合成了一系列茚并[2，3-b]喹啉类化合物．该反应产率高（83％～93％）、操作简单、后处理方便．产物的结构通过红外光谱、核磁共振谱和元素分析证实，同时给出了该反应可能的反应机理．
英文摘要：
A series of indeno[2,3-b]quinoline-5,11-diones were synthesized by the one-pot three component reaction of aromatic aldehydes, 1,3-indanedione and enaminones in acetic acid. This method has the advantage of high yields （83%-93%） and simple workup procedure. The structures of the products were identified by IR, ^1H NMR spectra and elemental analysis. In addition mechanism to account for the reaction was proposed.
