fluorescens ACB was employed in the presence of a weak anion exchange resin to perform dynamic kinetic resolutions of racemic benzyl ketones with high conversions and good optical purities. Different parameters that affect to the efficiency of the enzymatic Baeyer–Villiger oxidation and racemisation were analyzed in order to optimize the activity and selectivity of the biocatalytic system.

A set of racemic cyclic and linear ketones, as well as 2-phenylpropionaldehyde, were tested as substrates in the enzymatic Baeyer–Villiger oxidation catalyzed by two Baeyer–Villiger monooxygenases: phenylacetone monooxygenase (PAMO) and 4-hydroxyacetophenone monooxygenase (HAPMO). Excellent enantioselectivites (E > 200) can be obtained in the kineticresolution processes depending on the substrate

The enantioselective kineticresolution of two 3-phenyl-2-ketones using four different Baeyer–Villigermonooxygenases (BVMO) expressed recombinantly in Escherichia coli was studied. The highest enantioselectivity (E = 82) was achieved for 3-phenyl-2-butanone using a BVMO originating from Pseudomonas fluorescens. A BVMO from Pseudomonas putida showed an opposite (R)-enantiopreference and E = 12.
