摘要:
We report here a convenient synthesis of optically pure alpha-aryl amino acids by enantioselective substitution of fluorobenzene tricarbonylchromium using the Schiff bases of L-alanine methyl ester with (1R,2R,5R)-2hydroxy-3-pinanone in presence of LDA or deprotonated 2-(tert-butyl)-4-methyl-1,3-oxazolidin-5 one.
