Reaction of 3-alkyl(aryl)-5-chloromethylisoxazoles with nucleophilic reagents
摘要:
Previously unknown 3-alkyl(aryl)isoxazoles containing various functional groups in the 5-position were synthesized by reactions of 3-alkyl(aryl)-5-chloromethylisoxazoles with nucleophiles (2-aminoethanol, methylamine, sodium acetate, and sodium methoxide).
3-Chloro-2-isothiocyanato-1-propenyl alkyl(aryl) ketones react with hydroxylamine hydrochloride to give 3-alkyl(aryl)-5-chloromethylisoxazole. Treatment of the latter with dimethylamine and ammonium thiocyanate leads to formation of previously unknown 3-alkyl(aryl)-5-dimethylamino(or isothiocyanato)methylisoxazoles.
