Yb(OTf)3:通过亚氨基-狄尔斯-阿尔德反应合成3-芳基苯并[ f ]喹啉1,2-二羧酸酯衍生物的有效催化剂
摘要:
亚氨基-狄尔斯-阿尔德反应以高收率(76-92%)报道了一种温和而简便的合成3-芳基苯并[ f ]喹啉-1,2-二羧酸酯衍生物的方法。该方法包括在甲苯中由Yb(OTf)3催化的芳香醛,萘-2-胺和丁-2-炔二酸酯的新型三组分反应。结果明显不同于文献中由ZnCl 2或KOH催化的简单的取代苯胺参与的反应。
A wide variety of 3-arylbenzo[f]quinoline-1,2-dicarboxylates and their dehydro derivatives have been synthesized by one-pot, three-component reaction of an aromatic aldehyde, naphthalene-2-amine, and dimethyl but-2-ynedioate in the presence of SnCl2 under reflux in acetonitrile. This procedure has several advantages, for example high yield, short reaction time, easy work-up, little pollution, and low price of the catalyst.

An one pot simple and efficient approach toward the synthesis of dialkyl-3-aryl-3,4-dihydrobenzo[f]quinoline-1,2-dicarboxylate and its dehydro derivatives have been developed through the three-component reaction of aromatic aldehydes, 2-naphthylamine, and but-2-ynedioate catalyzed by SbCl3 under reflux in acetonitrile in good to excellent yields.

A mild and facile method for the synthesis of 3-arylbenzo[f]quinoline-1,2-dicarboxylate derivatives is reported by an imino-Diels–Alder reaction in high yields (76–92%). This procedure includes a novel three-component reaction of aromaticaldehyde, naphthalen-2-amine, and but-2-ynedioate catalyzed by Yb(OTf)3 in toluene. The results are obviously different from those of the simple substituted aniline-involved
