Convenient synthesis of 2,3-diaryl-4-thiazolidinones in aqueous SDS micelles

An efficient, rapid and green protocol has been developed for synthesis of 2,3-diaryl-4-thiazolidinones in aqueous micellar emulsion of anionic surfactant, sodium dodecyl sulphate (10 mol % SDS) at reflux condition. 11 examples leading to different 4-thiazolidinones are presented with a range of 77-85% of yields. Various substituted reactants are compatible with the developed procedure which shows versatility of the new synthetic method. The process is simple and high yielding.
