ABSTRACT:
A chiral .alpha.-amino acid having a hydrogen substituent in a position alpha to the carboxylic function thereof is prepared by subjecting a corresponding optical antipode with a chiral amino acid to a strong base whereby the proton in a position alpha to the carboxylic function is removed and thereafter reacting the resulting product with a chiral protonation agent.
