Reaction of sodium salts of O-methyl-N-substituted iminothiocarbonates with bromoacetyl bromide represents a new general method for preparation of 3-substituted 1,3-thiazolidine-2,4-diones in good yields and high purity. The structure of the synthesized products has been confirmed by 1H NMR, 13C NMR, IR and mass spectroscopy as well as by independent synthesis.

Keywords: Isothiocyanates; Iminothiocarbonates; 1,3-Thiazolidine-2,4-diones.
