Abstract Described here is the first example of Cu(0)-catalyzed intramolecular decarbonylative rearrangements of readily available N-aryl isatins assisted by solvent dimethyl sulfoxide (DMSO) under air atmosphere and additive-free conditions leading to various biologically important acridones in good to excellent yields. This novel transformation is proposed to go through a sequential DMSO-aided Cu
