The invention relates to (D)- or (L)-alpha-amino acids and their derivatives comprising phenylalanine or homophenylalanine having formula (I) or (II) and a process for the preparation thereof by stereoselective synthesis from aziridine having formula (V). The products maintain the stereochemistry of an optically pure aziridine used as starting material, and have many useful applications in industry.
