A simple and convenient procedure for the γ, β-dimerization of verbenone was developed. The dimer was obtained during aging with KOH without a solvent. The process proceeds as the formation of the extended enolate of verbenone and its Michael addition to other molecules of verbenone. The product yield was 82% after purification by column chromatography and recrystallization.
