Abstract   
 

            4-Chloro acetyl amino sulphamethaoxazole (A1) was synthesized by the reaction of amino sulphamethaoxazole with chloro acetyl chloride, Then refluxed with ammonium thiocyanate to obtain thiazoldine-4-one (A2) . (A2)  was stirred with formaldehyde and various secondary amines to gain 5 novel compounds Mannich bases(A3-7).and 2,5-Disubstituted thiazolidine-4-one (A8-11) were synthesized by the reaction of substituted benzyldehyd with Compound (A2) . The structure of the synthesized compounds are confirmed by I.R, 1H-NMR & 13C-NMR spectra and Some chemical physical data.
