BVMOs make a play: The dynamic kineticresolution of racemic α‐alkyl‐β‐ketoesters was performed through a selective Baeyer–Villiger oxidation employing different Baeyer–Villigermonooxygenases (BVMOs) in mild basic media. The product diesters were obtained with excellent yields and enantioselectivities, and used as precursors for optically active α‐hydroxy esters.
