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.

benzylic lithiums via an iodine–lithium exchange reaction on benzylic iodides performed in continuous flow using tBuLi as the exchange reagent. The resulting benzylic lithium species are trapped in situ by carbonyl electrophiles under Barbier conditions, resulting in benzylic secondary and tertiary alcohols. This flow procedure further allows the generation of highly reactive heterobenzylic lithium compounds
