Abstract: 1-Substituted (2S,4S)-4-amino-5-oxoprolines have been obtained by nucleophilic substitution of bromine in dimethyl (2S,4RS)-4-bromo-N-phthaloylglutamate followed by isolation of the predominant (2S,4S)-diastereomer and removal of protecting groups. The psychotropic activity of the obtained compounds has been studied after a single administration in experimental animals. 4-Amino-1-(4-bromophenyl)-5-oxoproline and especially 4-amino-1-(4-aminophenyl)-5-oxoproline showed pronounced anxiolytic activity in the Elevated plus maze test. (2S,4S)-4-Amino-5-oxoprolines containing 4-methylphenyl, 4-bromophenyl, 4?aminophenyl, and 2,3-dimethyl-5-oxo-1-phenyl-3-pyrazolin-4-yl substituents at the 1-position exhibited nootropic activity: they improved the formation and retention of the memory trace in the Passive avoidance test and the Active avoidance test (Extrapolation escape test).

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 p
