Condensation of two equivalents of o-vanillin with 4,4-dimethylcyclohexadienone (2) gives the five-ring ketone derivative (3). The reaction may be visualized as initial conjugate addition of phenoxide to the enone followed by interception of the resulting anion by the aldehyde carbonyl group. Catalytic hydrogenation then reduces both olefin pi-bonds as well as the ketone, to give (4). Re-oxidation of the alcohol thus formed with pyridinium chlorochromate affords pentomone.[2][3]
