The first practical synthesis of isoxazole triflones 3 (4-trifluoromethanesulfonylisoxazoles, 4-triflylisoxazoles) has been achieved by an operationally simple procedure consisting of the reaction between readily available α-triflyl ketones 4 and imidoyl chlorides 5 in the presence of triethylamine. The present method provides the biologically attractive isoxazoles featuring a triflyl group at the
异恶唑三氟甲磺酸酮 3(4-三氟甲磺酰基异恶唑,4-三氟甲磺酰基异恶唑)的第一个实际合成是通过操作简单的程序实现的,该程序由易于获得的 α-三氟甲磺酸酮 4 和亚胺酰氯 5 在三乙胺存在下的反应组成。本方法提供了具有生物吸引力的异恶唑,其特征是在 4 位具有三氟甲酰基的基团具有广泛的底物范围,在所有情况下都具有良好到高产率。
