Two component reaction for the synthesis of Quinolines in the presence of [gamma]-Al^sub 2^O^sub 3^ and Cu/ZnO nanoparticles

Two-component reaction of 2-aminobenzophenone with acetylenic esters in the presence of γ-Al^sub 2^O^sub 3^ and Cu/ZnO as suitable heterogeneous catalysts has been studied. Nano γ-Al^sub 2^O^sub 3^ and Cu/ZnO showed high activities when used as surface catalysts for the synthesis of quinoline derivatives. After completion of the reaction, the catalyst was recovered and reused several times under the same reaction conditions.
