afforded 1‐((3‐sub‐4‐oxothiazolidine) amino)‐azepine‐dione 14a‐c. The chemical structures of the new compounds have been confirmed by diverse spectroscopy analyses such as IR, NMR, MS, and elemental analysis. The synthesized compounds were tested for their antimicrobial activity and these compounds were considered (Pyridazin‐hydrazono‐thiazolidinone 13a‐c, oxothiazolidin‐azepinedione 14a‐c, N‐thia
