Abstract: | 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.For Communication 1, see 1].Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 8, pp. 1034–1038, August, 1989. |
