A convenient synthesis of 3-aroylisoxazoles from methyl ketones and (vinylsulfonyl)benzene in 2%TPGS-750-M/H2O has been developed. This reaction proceeds via tandem tert-butyl nitrite-promoted Csp3-H functionalization of methyl ketones, 1,3-dipolar cycloaddition and base-catalyzed aromatization, providing the corresponding products in moderate to good yields.
已经开发了在2%TPGS-750-M / H 2 O中由甲基酮和(乙烯基磺酰基)苯方便地合成3-芳基异恶唑的方法。该反应通过亚甲基串联叔丁基亚硝酸盐促进的Csp 3 -H官能化,1,3-偶极环加成和碱催化的芳构化进行,从而以中等至良好的产率提供相应的产物。
