higher enantioselectivity against 3-arylpent-4-enoic acid amides than 3-arylpentanoic acid amides. Under very mild conditions, nitrile biotransformations provided an efficient synthesis of highly enantiopure (R)-3-arylpent-4-enoic acids and (S)-3-arylpent-4-enoic acid amides, and their applications were demonstrated by the synthesis of chiral γ-amino acid, 2-pyrrolidinone, and 2-azepinone derivatives.
