Cyclohexene-1-Carboxylic acid (I) undergoes reaction with various aromatic substrates (2a-i) in presence of polyphosphoric acid (PPA) at 100°C to give cis-1,2,3,4,4a,9a-hexahydrofluoren-9-ones (3a-i) in good yield. Dehydrogenation of (3a-i) with selenium powder afforded corresponding fluoren-9-ones (4a-i) in high yield.
