Optically active α-arylglycine derivatives were synthesized by Brønsted acid (TFA)-promoted Friedel–Crafts reaction of various phenols with chiral cyclic glyoxylate imines (2a–c), followed by deprotection with Pd(OH)2/C under H2. The diastereoselectivities of the initially formed F–C reaction products are up to 99%.
