Herein, we report an intramolecular radical cyclization reaction towards the synthesis of pyrrolidinone derivatives via metal-free photoredox catalysis under irradiation from blue LEDs. Some of the remarkable features of this protocol include synthetic efficiency, green reaction profile, easy isolation of products and short reaction time. The photophysical properties of synthesized compounds were investigated
as a sulfonic acid-functionalized ionic liquid was demonstrated for the synthesis of pyrrolidinone derivatives under mild conditions. The electronic effect of substituents on aniline derivatives was investigated. Further, a study on the structure–activity relationship of ionic liquids containing sulfonic groups for the synthesis of ethyl-2-(4-chlorophenyl)-4-hydroxy-5-oxo-1-(p-tolyl)-2,5-dihydro-1H

novel and efficient protocol for the synthesis of pyrrolidinones using catalytic loading of 1,1'-butylenebis(3-sulfo-3H-imidazol-1-ium) hydrogen sulfate as a recyclable Brönsted acid ionic liquid through ball milling process at room temperature undersolvent-freeconditions. The developed method provides good to excellent yields of various pyrrolidinones in environmentally friendly conditions. Furthermore

The three-componentreactions of aromaticaldehydes, arylamines, and acetylenedicarboxylates show very interesting moleculardiversity. In an aqueous ethanol solution the three-componentreaction gave polysubstituted 2-hydroxyhydropyridines. In absolute ethanol 1,4-dihydropyridines were produced in satisfactory yields. Finally, under acid catalysis, this three-componentreaction afforded polysubstituted
Abstract An efficient one-pot, three-component synthesis of 3-pyrrolin-2-ones in aqueousmedia at room temperature is reported. This reaction provides a green and catalyst-free method for generation of 3-pyrrolin-2-one derivatives in good yields. GRAPHICAL ABSTRACT
