A novel catalyst-free, water-medium, tandem reaction for the
synthesis of 5-hydroxy-1,5-dihydro-2H-pyrrol-2-ones
was developed through a one-pot strategy from nitroethylenes and
1,3-dicarbonyl compounds. A series of 1-aryl-2-nitroethenes and
1-nitroalk-1-enes were surveyed to determine the scope of this tandem reaction
with moderate to good yield.
