Reaktionsschritte
Furthermore, J. J. Beereboom (U.S. Pat. No. 3,238,261 and J. Org. Chem., 31, 2026 (1966)) describes the reaction of methyl vinyl ketone with excess mesityl oxide in the presence of potassium hydroxide powder in tetrahydrofuran as the solvent. The piperitenone obtained is purified in a very expensive manner via the piperitenone-bisulfite adduct. In this process, yields of piperitenone of between 36 and 54% of theory are obtained.
