general synthesis of polycyclicheteroaromaticcompounds by generation of a quinonemethide in the presence of an aromatic amine has been successfully extended to naphthalene and phenanthrene ‘quinonemethides’. Whereas yields had been highest when the putative quinonemethides of less aromatic compounds were generated by a retro-Diels–Alder process, this method was inappropriate for the ‘quinone methides’

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.
