triphenylphosphine at −5°C led to (Z)‐methyl 2‐[(Z)‐2‐(4‐aroylimino)‐4‐oxo‐3‐aryl‐1,3‐thiazolidin‐5‐ylidene]acetates in good yields. The mechanism is discussed. X‐ray structure analysis of one thiazolidine derivative is described. Antitumor and antioxidant activities have been investigated. One derivative of 1,3‐thiazolidine showed moderate antiproliferative in vitro activity against hepatocellular carcinoma Hep‐G2

A series of 1,3-thiazines has been synthesized by the reactions of N-aroylsubstituted thioureas with ethyl propiolate, dimethyl but-2-ynedioate and (E)-1,4-diphenyl-but-2-ene-1,4-dione. The reaction of antipyrinylphenyl thiourea with π-deficient acetylenic reagents did not afford the corresponding 1,3-thiazines, whereas pyrrolo-pyrazolopyrimidines were obtained.

efficient heating source for organic synthesis, was recognized in the mid-1980s. Since then, numerous reactions with dramatically enhanced reaction rates have been disclosed,7 including the synthesis of thiazolidones.8 In view of the importance of thiazolidones and the advantages of microwave-induced reactions, it was thought worthwhile to attempt to synthesize the title compounds using microwave technique
