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

(R)- and (S)-3-hydroxy-4,4-dimethyl-1-phenyl-2-pyrrolidinone (R)- and (S)-1 have been prepared by lipase-catalyzed enantioselective acetylation of (S)-1 from rac-1 with vinyl acetate. Controlled hydrolysis of the acetate (S)-2 gave (S)-1. The configuration of (R)-1 and its p-bromobenzoate (R)-3 were established by X-ray diffraction analysis.
