Abstract

Abstract A novel one-pot thermal cycloaddition of two indenones followed by a decarbonylation and dehydrogenation cascade afforded benzo [c] fluorenones regioselectively. Various substituted indenone derivatives were converted into their corresponding benzo [c] fluorenones in good to excellent yields.
