Paragraph 0014; 0016, (2016/10/07)
The present invention discloses a new thiazolidinedione chemical compound preparation method. The synthetic route is shown in the description wherein R1 and R2 are H, CH3, MeO or t-Bu. The thiazolidinedione chemical compound synthesized by the new method is high in solubility and reactivity. Currently, such method has not yet been reported in the literature. The new method has the following advantages: the method is wide in applicability, short in reaction path, high in reaction efficiency, simple in after-treatment, low in cost, and suitable for industrial production.

This work reports the first application of diarylthiazolidin-2,4-diones as nucleophiles in asymmetric catalysis. By utilizing chiral amino acid-based (thio)urea-tertiary amines as the catalysts, we successively established asymmetric conjugate addition to nitroolefins and sulfenylation to N-(sulfanyl)-succinimides of diarylthiazolidin-2,4-diones. Two series of biologically important 5-aryl-5-substituted thiazolidin-2,4-diones were obtained with high enantio- and diastereoselectivities (up to >99% ee and >19:1 dr). The enantioenriched adducts were found to show satisfactory anticancer activities against three different cancer cell lines using the MTT assay. All of these successes depended on the development of a general and expedient synthetic strategy to provide diverse 5H-thiazolidin-2,4-diones.
