strategy for esterification of common amides using fluoride as a catalyst. This method shows high functional group tolerance, and notably it requires only a slight excess of the alcohol nucleophile, which is a rare case in transition‐metal‐free amide transformations. Moreover, this approach may provide a new understanding for further studies on esterification of amides and is expected to stimulate the development
近年来,已证明可以使用过渡金属催化剂活化并选择性裂解酰胺的碳氮键。但是,这些方法仅限于特定的酰胺。催化体系与酰胺之间存在一对一的关系,并且还使用大量的过渡金属催化剂和配体。因此,我们现在报告使用氟化物作为催化剂对普通酰胺进行酯化的一般策略。该方法显示出较高的官能团耐受性,尤其是仅需要略微过量的醇亲核试剂,这在无过渡金属的酰胺转化中很少见。而且,
