Cyclohexene-1-acetic acid (1) undergoes reaction with various aromatic substrates 2a-k in the presence of polyphosphoric acid (PPA) to give 1,2,3,4,4a,10a-hexahydrophenanthren-9(10H)-ones 3a-k by tandem acylation-cycloalkylation, which on dehydrogenation with Pd-C afforded the corresponding phenanthrenes 4a-k in high yields.
