Copper triflate catalyzed annulation of 2-aminoaryl ketones with internal alkynes has been developed for the synthesis of polysubstituted quinolines in high yields under solvent-free conditions. Phenyl propiolic acid afforded the 3-unsubstituted quinolines via decarboxylation. The protocol is compatible with various internal alkynes and is expected to find wide applications due to its operational simplicity.

intramolecular annulation of β-enamino esters is described under solvent-free, calcium-catalysis. 2-aminoaryl ketones and alkylpropiolates undergone a [4+2] annulation to yield substituted quinolines; with an excess of alkylpropiolates, benzodiazepines were formed via a [4+2+1] annulation. We also described a one-pot, 3-component synthesis of quinoline derivatives via a [4+2+2] annulation. Interestingly
