    • Olefin configurations for 3c-g were assigned based on the chemical shift values of the allylic protons, e.g., 2.11 ppm for (Z)-3c versus 2.60 ppm for the methyl ester of (E)-3c (ref 15a), as described by Denmark and Marcin (J. Org. Chem. 1993, 58, 3850-3856.).

    • In a preliminary experiment, E-3d was reduced by old yellow enzyme with largely (S)-stereoselectivity, as would be expected from the model in Scheme 2. This suggests that it may be possible to prepare the enantiomeric series of β-amino acids by using the alternate olefin isomers

    • The three byproducts were identified by GC/MS as (E)-3d, the alternate acrylate alkene regioisomer of 3d, and the water addition product from 3d (in racemic form).
