Ultrasound-Promoted One-Pot Synthesis of 7-Aryl-7,10,11,12-tetrahydrobenzo[c]acridin-8(9H)-one Derivatives

Abstract

Abstract A series of 7-aryl-7,10,11,12-tetrahydrobenzo[c]acridin-8(9H)-one derivatives were synthesized via the three-component coupling from aromatic aldehydes, 1-naphthylamine, and 5,5-dimethylcyclohexane-1,3-dione catalyzed by stannous chloride dihydrate (SnCl2 · 2H2O) under ultrasonic irradiation at room temperature. The products were isolated in good yields within short reaction times.
