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.
我们在这里报告了通过将α-氨基酯加到氟苯三羰基铬络合物中来方便地合成α-取代的芳基氨基酸的方法。通过使用L-丙氨酸,亮氨酸和缬氨酸甲酯的席夫碱和(1R,2R,5R)-2-羟基pinan-3-one的席夫碱对氟苯配合物进行对映选择性取代,制备了光学纯的α-芳基氨基酸。
