ABSTRACT The efficient and green Brønsted acid or Lewis acid catalysis systems for the Friedländersynthesis of 2,3,4-trisubstituted quinolines from the condensation of 2-aminoarylketones and β-ketoesters/ketones had been developed. The results confirmed that 4-toluenesulfonic acid, magnesium chloride, and cupric nitrate were the desired catalyst independently. This protocol had the advantages of mild

is in the interest of one‐pot, environmentally friendly and efficient protocol for the synthesis of quinoline derivatives from 2‐aminoarylketones and active methylene compounds in the presence of L‐proline and ionicliquid 1,3‐dimethylimidazolium methyl sulfate [MMIm][MSO4]. The Ionicliquid which is used as a catalyst can be reused several times. The results obtained by using [MMIm][MSO4] were also

A highly efficient and regioselective Friedlander reaction of unsymmetrical 1,3-diketones with 2-aminoaryl aldehydes (ketones) is described. The methodology leads to the synthesis of a broad scope of substituted quinolines in high yield and excellent regioselectivity. (C) 2012 Elsevier Ltd. All rights reserved.

The use of cerium(IV) ammonium nitrate as a catalyst of the Friedländer reaction allows the synthesis of polysubstituted quinoline derivatives in excellent yields, avoiding the traditional harshly basic or acidic conditions. Unlike most other previously known reagents, CAN allows double condensations and is also an excellent catalyst for the Borsche variation of the Friedländer reaction, which has
