A simple and efficientsynthesis of pyrrolo[2,3,4-kl]acridine-1-one derivatives via the cascade reaction of isatins with enaminones catalyzed by silicasulfuricacid (SSA) has been established. In this reactions, SSA shows a highly catalytic nature: easy to handle procedure, short reaction time, recycle exploitation, insensitivity to air and moisture, and excellent isolated yields. The catalyst could

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.
