Facile one-pot synthesis of chromeno[4,3-b] quinoline derivatives catalyzed by Cu(II)-Schiff base/SBA-15

Abstract

A novel, one-pot, simple, environmentally benign and efficient protocol has been employed for the synthesis of chromeno[4,3-b]quinoline derivatives in the presence of catalytic amounts of Cu(II)-Schiff base/SBA-15 under solvent-free conditions in excellent yields and rates.
