Abstract A novel copper(II) acetate mediated synthesis of 3-hydroxyphenanthridin-6(5H)-ones from N-(3-oxocyclohex-1-enyl)benzamides was developed. The process is postulated to involve an intramolecular oxidative C(sp2)–C(sp3) bond formation followed by dehydrogenative aromatization.

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.
