Copper(II)-Mediated Cascade Oxidative C-C Coupling and Aromatization: Synthesis of 3-Hydroxyphenanthridinone Derivatives

[摘要]：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(sp(2))-C(sp(3)) bond formation followed by dehydrogenative aromatization.
