Efficient, stereoselective approach to the synthesis of 3-(1-Phenyl-2-(Z-styrylsulfonyl)-1H-imidazol-4-yl)-2H-chromen-2-ones

Reaction of phenyl acetylene with 3-(1-aryl-2-mercapto-4-imidazolyl)-2H-1- benzopyran-2-ones (4) in the presence of sodium hydroxide in absolute ethanol led to the formation of 3-(1-phenyl-2-(Z-styrylthio)-1H-imidazol-4-yl)-2H- chromen-2-ones (6) in excel

α,β-UNSATURATED KETONES AND ANILIDES OF THE COUMARIN SERIES IN THE SYNTHESIS OF ISOXAZOLE, IMIDAZOLE, AND PYRAZOLE DERIVATIVES

Coumarin-containing unsaturated ketones react with bromine to give dibromides, which form derivatives of isoxazoles and pyrazoles via reaction with hydroxylamine hydrochloride or phenylhydrazine.A method for preparing coumarin-containing imidazoles from the corresponding anilides was elaborated.
