prepared in good yields and excellent enantiomeric purity by enzymatic kinetic resolution using CAL-B and ethyl methoxyacetate as the acyl donor. In the case of the 4-hydroxyderivative of amphetamine (compound 4i), the S enantiomer racemized possibly in a dynamic kinetic resolution (DKR) under the enzymatic conditions used.
