exceptional level of sophistication in cross‐coupling chemistry, reactions of substrates that incorporate the leaving group as an integral part into a heterocyclic scaffold are scarce. The title reaction outlines the utility of this reaction format (see scheme; acac=acetylacetonate), provides a convenient entry into stereodefined diene carboxylates, and adds a new chapter to the field of iron catalysis.
开放获取:尽管交叉偶联化学的复杂程度非常高,但将离去基团作为整体组成部分整合到杂环支架中的底物的反应却很少。标题反应概述了该反应形式的用途(参见方案; acac =乙酰丙酮化物),为立体定义的二烯羧酸盐的合成提供了便利,并为铁催化领域增添了新篇章。
