Stereoselective synthesis of both enantiomers of N-Boc-α-aryl- γ-aminobutyric acids

Esterification of racemic α-aryl-β-cyanopropionic acid chlorides with either (R)- or (S)-N-phenylpantolactam as the chiral auxiliary in the presence of Et3N resulted in the predominant formation of (αR,3′R)- or (αS,3′S)-configured pantolactam c
