A new general synthesis of quinolines was developed from ketoximes and alkynes in the presence of Tf2O. It offered the first direct synthesis of quinolines by using the nitrilium salts generated in situ from a Tf2O‐promoted Beckmann rearrangement of ketoximes under very easy conditions.
A MOF-5-catalyzed three-componentcouplingreaction was developed as an efficient approach for the synthesis of 2,4-disubstituted quinoline derivatives via a one pot three-componentreaction of aromatic amines, aldehydes and alkynes with excellent yields. The easy recovery and reusability of the catalyst, broad substrate scope, short reaction time, high yields of products and solvent-free conditions

the iron-catalyzed oxidative cyclization of alcohol/methyl arene with 2-amino styrene to synthesize polysubstituted quinoline. Low-oxidation level substrates such as alcohols and methyl arenes are converted to aldehydes in the presence of an iron catalyst and di-t-butyl peroxide. Then, the quinoline scaffold is synthesized through imine condensation/radical cyclization/oxidative aromatization. Our

FeCl3‐catalyzed three‐component tandem condensation/addition/cyclization/oxidation reactions of aldehydes, terminal alkynes, and primary amines have been developed. The processes can provide a diverse range of quinoline derivatives in good yields from simple starting materials. A possible reaction mechanism was proposed. J. Heterocyclic Chem., (2010).
