On the basis of the results obtained from NMR spectroscopy, X-ray analysis and chemical transformations, it was established that acidic hydrolysis of (2S,4S)-4-arylaminoglutamates results in the formation of lactams in which ring closure occurs with the participation of the γ-amino and α-COOH groups; but isomeric lactams resulting from the participation of the α-amino and γ-COOH groups are not formed

(2S,4S)-4-Arylamino-2-carboxy-5-pyrrolidones were prepared by hydrolysis of dimethyl (2S,4S)-4-arylamino-N-phthaloylglutamtaes. The protonation constants of the arylamino group in the synthesized compounds were determined. The pyrrolidone ring is stable in acidic or neutral solutions. The relative stability of the pyrrolidone ring in alkaline solutions was studied by IR spectroscopy.
