demonstrated that amides can be used in nickel‐catalyzed reactions that lead to cleavage of the amide C−N bond, with formation of a C−C or C−heteroatom bond. However, the general scope of these methodologies has been restricted to amides where the carbonyl is directly attached to an arene or heteroarene. We now report the nickel‐catalyzed esterification of amides derived from aliphatic carboxylic acids
最近的研究表明,酰胺可用于镍催化的反应中,从而导致酰胺C-N键断裂,并形成C-C或C-杂原子键。但是,这些方法的一般范围仅限于酰胺,其中羰基直接连接到芳烃或杂芳烃上。现在我们报告衍生自脂肪族羧酸的酰胺的镍催化酯化反应。该转化仅需要稍微过量的醇亲核试剂,并且可以耐受杂环,具有差向异构立体中心的底物和空间上拥挤的偶联配偶体。此外,一系列酰胺竞争实验建立了选择性原理,将有助于未来的合成设计。
