A MsOH-catalyzed oxidative cross-coupling of acridans and silyl diazoenolates and a Rh2(OAc)4-catalyzed rearrangement of the resultant diazo products are described. The reactions provide various γ-(9-acridanylidene)-β-keto esters in good yields, which bear an active α-methylene unit for further functionalization.

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 insertion into the amide C–N bond, CO extrusion, Cu migration, reductive elimination and DMSO-aided proton migration processes, involving multiple types of bond cleavage and formation in a single chemical step.
