chemistry and the construction of this motif with high atom economy is the focus of the current research. Specifically, N-methyl amides are valuable building blocks in natural products and pharmaceutical science. Due to the volatile nature of methyl amine, the generation of N-methyl amides using simple acids with high atom economy is rare. Herein, we disclose an atom economic protocol to prepare this
酰胺是存在于有机化学各个领域分子结构中的基本基团,构建具有高原子经济性的这一基序是当前研究的重点。具体来说,N-甲基酰胺是天然产物和药物科学中有价值的组成部分。由于甲胺的挥发性,使用具有高原子经济性的简单酸生成N-甲基酰胺的情况很少见。在此,我们公开了一种原子经济方案,用于在 DABCO/Fe 3 O 4协同催化下制备这种有价值的基序。该协议操作简单,与一系列脂肪族和(杂)芳族酸兼容,产率非常高(60-99%)。此外,Fe 3 O4可以很容易地回收并保持高效率长达十个周期。
