Iron/acetic acid-mediated carbon degradation: a facile route for the synthesis of quinoline derivatives
摘要:
A new carbon degradation protocol which results in the formation of quinoline derivatives is described. The reactions involved the use of mild reaction conditions and an inexpensive reducing reagent (Fe/AcOH). (C) 2010 Elsevier Ltd. All rights reserved.
has been shown that acid catalysis is more effective than base catalysts for the Friedlander annulation. In recent years, Bronsted and Lewis acids such as ionicliquids, sulfamic acid, hydrochloric acid, zirconium tetrakisdodecyl sulfate [Zr(DS)4], 29 silica sulfuric acid, silica supported phosphomolybdic acid [PMA.SiO2], 32 nanocrystalline aluminium oxide, dodecylphosphonic acid (DPA), poly(N-bromoethylbenzene-1
A rapid and efficient method for the synthesis of various poly-substituted quinolines has been developed via the Friedländer condensation of 2-aminoarylaldehyde with a carbonyl compound containing a reactive α-methylene group in the presence of sodium ethoxide (10 mol %). The new tetrahydroacridine derivatives and 11H-indeno[1,2-b]quinolines were synthesized in high yield with sodium ethoxide as a
在乙醇钠(10摩尔%)存在下,通过2-氨基芳基醛与含有反应性α-亚甲基的羰基化合物的Friedländer缩合反应,已经开发出一种快速有效的合成各种多取代喹啉的方法。以乙醇钠为催化剂,通过Friedländer反应,高收率合成了新的四氢ac啶衍生物和11 H-茚并[1,2- b ]喹啉。讨论了反应条件,并提出了可能的反应机理。
