A short chemoenzymatic synthesis of β-aryl-γ-aminobutyric acids has been developed, based on a highly enantioselective biocatalytic reduction of β-aryl-β-cyano-α,β-unsaturated carboxylic acids.

The Trp 116mutants of OldYellowEnzyme1 that catalyse the reduction of (Z)‐β‐aryl‐β‐cyanoacrylates give the oppositeenantioselectivity according to the nature of the amino acid in position 116. Small amino acids (e.g., alanine) make the substrate bind to the enzyme′s active site in a “classical” orientation, affording the (S)‐enantiomer of the reduced product. When the size of the amino acid increases
