In this research a number of pyrrolidine-2-one derivatives were prepared by lactamization of γ –butyrolactone (GBL) with hydrazine hydrate (80%) to produce (1-aminopyrrolidine-2-one) that undergoes several reactions to afford these derivatives that diagnosed by infrared, nuclear magnetic resonance and mass spectroscopy. Antibacterial activity has also been studied using some types of bacteria, some were found to have good antibacterial activity.
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.
New derivatives of pyrrolidine-2-one have been prepared by lactamization of -butyrolactone GBL with hydrazine hydrate (NH2NH2(80%)) to afford (1-aminopyrrolidin-2-one) which undergo many reactions to prepare the other derivatives. The prepared derivatives were determined by utilizing their FT-IR,1H-NMR and some by Mass spectrum. These derivatives were evaluated biologically against (Staphylococcus aureusand E. coli).Some of these derivatives exhibited good biological activity against one or both kind of bacteria while some exhibited no biological activity at all.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
