- I2/TBHP-Mediated tandem cyclization and oxidation reaction: Facile access to 2-substituted thiazoles and benzothiazoles
-
The efficient synthesis of 2-substituted thiazoles and benzothiazoles has been accomplished employing readily available cysteine esters and 2-aminobenzenethiols as N and S sources. The reaction proceeds under an I2/TBHP system and involves a on

- Oxidation of 4-carboxylate thiazolines to 4-carboxylate thiazoles by molecular oxygen
-
A facile and environment-benign oxidation by molecular oxygen was applied for the conversion of 4-carboxylate thiazolines to 4-carboxylate thiazoles. The substituent effect on thiazoline ring was investigated. It was found that electron-poor group on the thiazoline ring could facilitate the oxidation.

- Derivatives of 2-(iminomethyl)amino-phenyl, their preparation, their use as medicaments and the pharmaceutical compositions containing them
-
The invention relates to new derivatives of 2-(iminomethyl)amino-phenyl which are NO synthase inhibitors and can trap reactive oxygen species. These compounds can notably be used for the treatment of stroke, of neurodegenerative diseases and of ischemic or hemorragic cardiac or cerebral infarctions. These compounds include: N-{4-[({[4-(3,5-di-tert-butyl-4-hydroxyphenyl)-1,3-thiazol-2-yl]methyl}amino)methyl]phenyl}thiophene-2-carboximidamide; N-{3-[({[4-(3,5-di-tert-butyl-4-hydroxyphenyl)-1,3-thiazol-2-yl]methyl}amino)methyl]phenyl}thiophene-2-carboximidamide; N-(4-{[{[4-(3,5-di-tert-butyl-4-hydroxyphenyl)-1,3-thiazol-2-yl]methyl}(methyl)amino]methyl}phenyl)thiophene-2-carboximidamide; N-[3-({[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propyl]amino}methyl)phenyl]thiophene-2-carboximidamide; N-(3-{[(3,5-di-tert-butyl-4-hydroxybenzyl)amino]methyl}phenyl)thiophene-2-carboximidamide; N-[3-({[2-(3,5-di-tert-butyl-4-hydroxyphenyl)ethyl]amino}methyl)phenyl]thiophene-2-carboximidamide; N-[3-({[3-(4-hydroxy-3,5-diisopropylphenyl)propyl]amino}methyl)phenyl]thiophene-2-carboximidamide; N-(3-{[(4-hydroxy-3,5-diisopropylbenzyl)amino]methyl}phenyl) thiophene-2-carboximidamide; N-[3-({[2-(4-hydroxy-3,5-diisopropylphenyl)ethyl]amino}methyl)phenyl]thiophene-2-carboximidamide; N-2-(3,5-di-tert-butyl-4-hydroxybenzoyl)-N-1-(4-{[imino(thien-2-yl)methyl]amino}phenyl)-L-leucinamide; and pharmaceutically acceptable salts thereof.
