Abstract

Abstract Racemic α-chiral primary amines were deracemised to optically pure amines in up to> 99% conversion and> 99% ee within 48 h. The deracemisation was a result of a stereoinversion of one amine enantiomer; the formal stereoinversion was achieved by a one- pot, two-step procedure: in the first step, kinetic resolution of the chiral racemic amine was performed by employing a ω-transaminase to yield an intermediate ketone and the ...
