Interaction of 1,5-Substituted Pyrrolin-2-ones with Dichlorocarbene under Phase Transfer Catalysis Conditions

Abstract

Treatment of 5-alkyl(aryl)-3H-pyrrolin-2-ones with dichlorocarbene under phase transfer catalysis conditions at 20-30ºC results in a cycloaddition of the carbene to the C=C bond followed by skeletal rearrangement.
