Regioisomeric lactones (ee98%) were obtained by microbiological Baeyer-Villiger oxidation of enantiomers of menthone and dihydrocarvone. The regioselectivity of the biotransformation is shown to be dependant upon the considered enantiomer. An improvement of our empirical model of the active site is suggested.

Recombinant whole-cell expression systems for BaeyerâVilliger monooxygenases of various bacterial origin were utilized in the regiodivergent biooxidation of cyclic terpenones enabling access to enantio- and regioisomeric lactones on preparative scale.
