This work presents the first chemical approach for the resolution of α-amino acids offering the following advantages: (1) The specially designed resolving reagent is derived from α-(phenyl)ethylamine, the most inexpensive chiral auxiliary, which can be recycled and reused, rendering the cost structure of the complete process very attractive; (2) the time-efficient two-step process can be conducted
