A facile and efficient approach toward the synthesis of functionalized quinolines and 1,2‐dihydroquinolines from carbonylcompounds and 2‐vinylanilines is described. The protocol utilizes the nonhazardous and less expensive FeCl3 as catalyst with wide functional group tolerance and avoiding heavy metal impurities in the products.
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

microwave-assisted synthesis of substituted quinolines is described. The quinolines were synthesized by a multicomponent domino reaction of anilines, aldehydes and terminal aryl alkynes. The synthetic pathway involves the formation of an imine, followed by the intermolecular addition of an alkyne to the imine. This intermediate immediately undergoes ring closure and oxidative aromatization. The reaction is catalyzed
