Article abstract of DOI:10.1007/BF00479600

Reaction of 5-aryl-4-halo-2,3-dihydrofuran-2,3-diones with alkoxycarbonylmethylenetriphenylphosphoranes has given 2-alkoxycarbonylmethylene-5-aryl-4-halo-2,3-dihydrofuran-3-ones, which readily add halogens at the 2-exocyclic double bond, and on reaction with arylamines recyclize to give 2-hydroxy-2,3-dihydropyrrol-3-ones.
