reflux to afford the corresponding 2-alkoxy-2-trichloromethylthiazolidin- 4-one derivatives 7a-l. Reaction of compounds 1a-d with trichloroacetonitrile or other nitriles 11a-c in refluxing glacial acetic acid gave 5-arylmethylene-2,4-thiazolidinediones 8a-d. The structures of all the newly synthesized products were confirmed based on elemental and spectral data, and a plausible mechanism is postulated to
