An efficient domino approach for the synthesis of novel pyrrolo[2,3,4-kl]acridin-1-one derivatives has been established. This reaction represents the first facile conversion of an isatin to a pyrrolo[2,3,4-kl]acridin-1-one via a C N bond cleavage reaction without the reed for a multistep reaction process.

A improved and efficient procedure for the synthesis of pyrrolo[2,3,4‐kl]acridin‐1‐one derivatives via the reaction of isatin and enaminone catalyzed by ceric ammonium nitrate under ultrasonic condition has been developed. Compared with the conventional methods, the remarkable advantages of this method are mild reaction conditions, operational simplicity, higher yield, and shorter reaction times.
