Synthesis of quinoline derivatives from the reaction of aminobenzophenones and acetylenic esters in the presence of SnO2 nanoparticles

Abstract

Nano SnO 2 catalyzes the two-component reaction of 2-aminobenzophenones with acetylenic mono or diesters under mild conditions to afford quinoline derivatives in high yields. Nano SnO 2 shows high activity when used as surface catalyst for the synthesis of quinoline derivatives.
