In our effort to obtain biologically active compounds, new 3,5-disubstituted 1,3-thiazolidine-2,4- diones (5a - r) were synthesized. A series of 5-arylmethylidene-1,3-thiazolidine-2,4-diones (3a - r) were prepared by Knoevenagel reaction from 1,3-thiazolidine-2,4-dione (2) and appropriate aromatic aldehydes. Condensation of 3a - r with 7-hydroxy-4-bromomethyl-2-oxo- 2H-chromene (1) afforded novel 3-(7-hydroxy-2-oxo-2H-chromen-4-ylmethyl)-5- arylidene-1,3-thiazolidine-2,4-diones 5a - r. Compounds 3a - r and 5a - r were evaluated for their antioxidant activity (DPPH free radical scavenging activity).
