The synthesis of enantiomerically enriched a-amino acids is described, by means of the diastereoselective conjugate addition of Grignard reagent to (S)-2-acetamidoacrylic ethoxycarbonylphenyl-methyl ester 1 and its N-Boo derivative 5 in the presence of Lewis acids. The addition of magnesium organocu
