Enantioselective kinetic resolution of 3-phenyl-2-ketones using Baeyer–Villiger monooxygenases

The enantioselective kinetic resolution of two 3-phenyl-2-ketones using four different Baeyer–Villiger monooxygenases (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.
