Three series of new thiazolidinone derivatives, namely 5-arylidene-4-thiazolidinones (6a6j), 4-thiazolidinethione (7a7e and 8) and 4-cyanoiminothiazolidine (11a11e and 12) were synthesized from 2-substituted-3-aryl-4-thiazolidinones (4a4e and 5). The intermediates 4a4e and 5 were synthesized by the condensation of aldehyde, amine and mercapto acetic acid. Their structures were characterized by elemental analysis and 1H NMR spectra, and the structure of 4b was determined by X-ray single crystal diffraction method. The preliminary bioassay showed that some title compounds exhibited certain fungicidal activities and promoting cucumber cotyledon root-formation activities.
