Novel β-lactam derivatives (1c-3c, 1d-3d) were synthesized by acylating of 6-APA and 7-ACA with the higher amino acid Schiff bases (1b-3b).
The molecular structures of the β-lactam derivatives were determined by spectroscopic methods.
Antimicrobial activities of all compounds (1a-3a, 1b-3b, 1c-3c, 1d-3d) were investigated by the broth microdilution method.
