Provided are compounds and salts having a structure of Formula (I) or (II): (I), and (II) wherein: both of the chiral carbon atoms denoted by "*" are both in the R configuration or both in the S configuration. Compounds and salts of Formulae (I) and (II) are useful in the preparation of enantiomerically pure amino acids. Conversion of amino acids to D-form from any of L-form, racemate or other enantiomerically impure mixtures or conversion of amino acids to L-form from any of D-form, racemate or other enantiomerically impure mixtures is disclosed.
