2‐phenylpropanal and a substituted 2‐methyl‐3‐phenylpropanal: the corresponding N‐methylated β‐chiral amines were obtained with >95 % conversion and 78 and 95 %ee. Other amines were formed with low to moderate enantiomeric excess. This exemplifies the potential of IREDs for the one‐step synthesis of secondary β‐chiral amines, but also the challenge to identify highly selective enzymes for a desired amine
