Abstract

A microwave-assisted, chemoselective synthesis of the novel antitumor and antimicrobial (3E)-5-hydroxy-1-isopropyl-3-[(5-methyl-2-thienyl)methylene]-5-phenylpyrrolidin-2-one has been achieved via assisted microwave solvent-free one-pot reaction of (3E)-3-[(5-methyl-2-thienyl)methylene]-5-phenylfuran-2(3H)-one with amines, urea and thiourea. The products are obtained in significant purity, yield, and eco-friendly reaction conditions. The structural formula of the products is confirmed by their spectroscopic characterizations.  A mechanism is proposed in which an intramolecular nucleophilic attack takes place on the carbonyl carbon by the lone pair of electrons on the nitrogen atom, leading to ring closure with proton transfer to oxygen forming the hydroxyl group.
