Friedländer synthesis - Wikipedia

WebThe Friedländer synthesis is a chemical reaction of 2-aminobenzaldehydes [1] with ketones to form quinoline derivatives. [2] [3] It is named after German chemist Paul Friedländer (1857–1923). This reaction has been catalyzed by trifluoroacetic acid, [4] toluenesulfonic acid, [5] iodine, [6] and Lewis acids. [7] Several reviews have been ... The Combes quinoline synthesis is a chemical reaction, which was first reported by Combes in 1888. It involves the condensation of unsubstituted anilines (1) with β-diketones (2) to form substituted quinolines (4) after an acid-catalyzed ring closure of an intermediate Schiff base (3). Further studies and reviews of the Combes quinoline synthesis and its variations have been published by Alyamki…
