Abstract

Novel Thiazolidin-4-one Synthesis of 3-(2-(1,1-dioxido-1,2- thiazetidin-2-yl)ethyl)-2-phenylthiazolidin-4-one 8 (af) were synthesized by condensation reaction between synthesis of 2-(2-(4-substituted benzylideneamino)ethyl)-1,2- thiazetidine 1,1-dioxide 6(a-f) and a mixture of mercaptoacetic acid and anhydrous Zinc chloride. Synthesis of 2-(2- (4-substituted benzylideneamino)ethyl)-1,2-thiazetidine 1,1-dioxide 6(a-f) was condensed with 4-substituted benzaldehyde in absolute alcohol. The synthesis of 2-(2-aminoethyl)-1,2-thiazetidine 1,1-dioxide(4) was synthesized by condensation of synthesis of 1,2-thiazetidine 1,1-dioxide (β-Sultam)(3) a mixture of K2CO3, TEBA , Acetonitile and 2-chloro ethanamide. Synthesis of 1,2-thiazetidine-1,1-dioxide(β-Sultam) (3) was synthesized with Taurinesulfonylchloride (2) with Na2CO3, Ethyl acetate. Taurinesulfonylchloride (2) was synthesized by S-S bond cleavage Cystaminedihydroxychloride (1) with mixture of Chlorine gas, Chloroform and Ethanol solvent mixture.
