A mild and efficient method for the synthesis of 8,9‐dihydro‐11‐aryl‐7H‐cyclopenta[b][4,7]phenanthrolin‐10(11H)‐onederivatives via three‐component reaction of aromatic aldehyde, quinolin‐6‐amine and cyclopentane‐1,3‐dione is described catalyzed by Yb(OTf)3. The features of this procedure are mild reaction conditions, good to high yields, and operational simplicity.
