non‐natural N‐Boc‐amino acid thioesters undergo enzyme‐catalyzed ammoniolysis and aminolysis with concomitant base‐catalyzed racemization of the non‐transformed D‐enantiomer with the formation of the corresponding L‐amides in good yields and excellent enantiomeric purity all above 98% ee. This is the first example of a dynamickineticresolution of amino acid derivatives with amides formation.
