摘要: This work presents the first chemical approach for resolution of α-amino acids offering following advantages: (1) The specially designed resolving reagent is derived from α-(phenyl)ethylamine, most inexpensive chiral auxiliary, which can be recycled and reused, rendering cost structure complete process very attractive; (2) time-efficient two-step conducted under operationally convenient conditions with virtually quantitative yields; (3) readily adapted to large-scale use.
