The oxidation of terpene olefins with hydrogen peroxide in the presence of the non-hemo catalyst 5a afforded mixtures of epoxides whose composition was dependent upon the oxidation protocol used in each case. With terpenoid enones, the mixtures obtained evolved from clean epoxidation of α-ionone 23 to the clean allylic oxidation of damascone 28 due to the progressive deactivation of the electron density

constituents, being also appreciated as synthetic building blocks. This work shows the ability of unspecificperoxygenases (UPOs, EC1.11.2.1) from several fungi, some of them being described recently, to catalyze the oxyfunctionalization of α- and β-ionones and α- and β-damascones. Enzymatic reactions yielded oxygenated products such as hydroxy, oxo, carboxy, and epoxy derivatives that are interesting
Use of oxygenated alicyclic compounds, some of which are new, as perfuming and/or flavouring ingredients in the manufacture of perfumes and perfumed products and/or in the preparation of artificial flavours for foodstuffs, animal feeds, beverages, pharmaceutical preparations and tobacco products. Process for the preparation of said alicyclic compounds.
