An efficient and operationally simple method for the synthesis of N-acyl sulfamates from fluorosulfonates and potassium trimethylsilyloxyl imidates as amide precursor is reported. This approach showed broad substrate scope, mild and base-free reaction conditions, short reaction time, and high to excellent yields. Notably, we demonstrated the power of this reaction in the rapid late-stage functionalization
报道了一种由氟磺酸盐和三甲基甲硅烷基氧基亚氨酰亚胺盐作为酰胺前体合成N-酰基氨基磺酸盐的有效且操作简单的方法。这种方法显示出广泛的底物范围,温和且无碱的反应条件,短的反应时间以及高到极好的收率。值得注意的是,我们证明了该反应在三个复杂的含酚生物活性分子的快速后期功能化中的作用。考虑到含酚药物和构件的流行,该方法适用于面向多样性的药物发现。
