Monoamine Oxidase–ω‐Transaminase Cascade for the Deracemisation and Dealkylation of Amines

Abstract Herein we report a one‐pot protocol for the deracemisation of chiral benzylic amines employing a novel monoamine oxidase–ω‐transaminase cascade, allowing access to enantiopure compounds in >99 % ee . We also demonstrate that the same enzymatic cascade can be employed for the dealkylation of secondary amines with >99 % conversion.
