    Abstract: The present disclosure relates to chemo-enzymatic processes for the preparation of lactones (including, e.g., macrolactones, γ-lactones, and δ-lactones) and/or macrocyclic ketones, which are compounds of industrial value, for example, for use as fragrance ingredients. The chemo-enzymatic processes combine the in vivo microbial production of fatty acid derivatives and the subsequent ex vivo synthetic transformation of the fatty acid derivatives to provide the lactones and macrocyclic ketones.
