2-Formylchromones and 3-formylchromones as the first materials singly reacted with 2-amino-5-mercapto-1,3,4-thiadiazole to give the corresponding Schiff bases, which on cyclocondensation with mercaptoacetic acid in 1,4-dioxane yielded target compounds named 4-oxo-thiazolidines. The structures of all the synthetic compounds were confirmed by elemental analysis and IR, 1 H NMR, LC-MS (ESI) spectral data
