Synthesis of substituted maleimide derivatives using the Baylis–Hillman adducts

The Baylis–Hillman alcohols, 3-ethoxycarbonyl-3-hydroxy-3-aryl(alkyl)-2-methylenepropanenitriles, derived from α-keto esters and acrylonitrile, have been conveniently transformed into 3,4-disubstituted 1Hpyrrole-2,5-dione (maleimide) derivatives on treatment with FeCl3/RCO2H in a one-pot operation....
