been revealed. This cascade reaction involved a Michael addition/intramolecular cycloaddition/dehydration and provided the desired benzo[4,5]imidazo[1,2-a]pyridines in moderate to good yield. Furthermore, three benzo[4,5]imidazo[1,2-a]pyridines (3d, 3i, and 3q) exhibited good activities against Hep-G2 (human liver cancer), T-24 (human bladder cancer cell), and SK-OV-3 (human ovarian cancer) cell lines
