Synthesis of Some New Derivatives of Pyrrolidine-2-one and Studying Their Antibacterial Potentials
New derivatives of pyrrolidine-2-one have been synthesized through lactamization of γ –butyrolactone (GBL) by hydrazine hydrate (80%), ethylene diamine and ethanol amine to afford compounds (1-aminopyrrolidin-2-one), (1-(2-aminoethyl)pyrrolidine-2-one) and (1-(2-hydroxyethyl)pyrrolidine-2-one), respectively. Compound (1-aminopyrrolidin-2-one) underwent several reactions to synthesize the rest of these derivatives. All synthesized compounds were approved by their FT-IR, 1H-NMR and some by Mass spectra. The biological activities of these derivatives were evaluated against Escherichia coli and Staphylococcus aureus. Many of these derivatives showed moderate biological activity against one or both kind of bacteria in comparison to amoxicillin and some showed no biological activity at all.
