Abstract

Pre‐grown mycelia of Lasiodiplodia theobromae ATCC 28570 transform β‐ionone (1) into a large variety of metabolites, by mainly degrading the side‐chain of the β‐ionone molecule by a C~2~‐unity. The enzyme system responsible for this degradation is proposed to be an oxygenase, which gives rise to the formation of the main product β‐cyclo‐homogeraniol (8) in analogy to a Baeyer‐ Villiger oxidation. Further enzymic actions of Lasiodiplodia such as hydrogenations and hydroxylations lead to an accumulation of several not yet described β‐ionone metabolites.
