The enzymatic kinetic resolution of a broad set of β‐amino ketones was investigated by using a collection of 16 Baeyer–Villigermonooxygenases from different bacterial origins, which display various substrate specificities. Within this platform of enzymes excellent enantioselectivities (E>200) were found towards aliphatic and aromatic 4‐amino‐2‐ketones, and some enzymes even showed opposite enantioselectivity

To the left or to the right? The regioselective insertion of oxygen in Baeyer–Villigermonooxygenase (BVMO) catalyzed oxidations not only affords the expected protected β‐amino alcohol, but can also be used to provide access to β‐amino acids as exemplified for β‐leucine (see scheme; PG=protecting group).
