Abstract

Oxidation of β,γ-Unsaturated Ketones with Molecular Oxygen Catalyzed by Metal Phthalocyanines and Porphyrins: A Practical Synthesis of Oxophorone.-A simple method for the oxidation of β-isophorone (III) to oxophorone (IV), an important key intermediate for the synthesis of carotenoids, is presented. This method can also be applied to the oxidation of acyclic unsaturated ketones (V). Compound (VIa) is an aggression controlling substance in bees.-(ITO, N.; ETOH, T.; HAGIWARA, H.; KATO, M.; Synthesis (1997) 2, 153-155; Res. Dev.
