Abstract: | Novel spiro-isatin-thiazolidino-pyrazoline compounds containing alkoxyphthalimide moiety have been synthesized through a four step pathway starting from chalcone 1a-e. Cyclization of these with hydrazine hydrate in absolute ethanol have yielded 1-acetyl-3-(4-aminophenyl)-5-(4-substituted phenyl)-2-pyrazoline 2a-e. Acid catalyzed condensation of 2a-e with isatin 3 has yielded 3-[4-{1-acetyl-5-(4-substituted phenyl)-2-pyrazoline-3-yl}phenylimino]indole-2-one 4a-e. These Schiff bases on reaction with mercaptoacetic acid in presence of anhydrous ZnCl2 gave their corresponding spiro-thiazolidinone derivatives 5a-e. Subsequent treatment with bromoethoxyphthalimide yielded titled compounds 3'-{4-(1-acetyl-5-(4-substituted phenyl)-2-pyrazoline-3-yl)phenyl}-1-N-ethoxyphthalimido-4'H-spiro[indole-3,2'-[1,3]thiazolidene]-2,4'-1H-dione 6a-e. |
