Reactions of fluorobenzene tricarbonylchromium complexes with anions from Schiff bases of α-amino esters; enantioselective synthesis of α-aryl amino acids
We report here a convenient synthesis of α-substituted aryl amino acids via the addition of α-amino esters to fluorobenzene tricarbonylchromium complexes. Optically pure α-aryl amino acids have been prepared by enantioselective substitution of fluorobenzene complexes using Schiff bases of L-alanine, leucine and valine methyl esters and (1R,2R,5R)-2-hydroxypinan-3-one.
