The base catalyzed isomerization of 2-(aroyl-methylene)-3-aryl-thiazolidine-4,5-dione derivatives 1 leads to salts of 1-aryl-3-aroyl-4-hydroxy-pyrroline-2-thio-5-one and aliphatic amines 2.It was found that 2 undergo further transformation to 4-thioanilido-5-arylo-2,3-furanodione derivatives 4.This series of reaction provides a convenient synthetic route to 2,3-furanodione derivatives 4. - Keywords: 2,3-Furanodiones; Thiazolidine-4,5-diones
