WebJan 1, 2024 · The quinoline scaffold is present in numerous alkaloids and bioactive compounds often associated with remarkable biological properties. Common approaches to assemble the quinoline ring system include the Skraup, Friedländer, Combes, Doebner-von Miller, and Conrad-Limpach reactions, but the utility of these synthesis methods is … 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…
