摘要

在此，我们报告了通过镍催化烯烃羟基芳基化和分子内依次内酯化，以 O2 作为绿色氧化剂和氧源制备内酯的过程。笨重的 1,3-二酮配体在镍催化烯烃羟基芳基化反应中发挥了关键作用，在温和的条件下高效地提供了大量邻苯二甲酸酯和呋喃酮衍生物。这种方法的合成价值通过高效合成萘酞和一种单胺氧化酶 B 抑制剂得到了进一步证明。

Construction of Lactones via Ligand-Enabled Ni-Catalyzed Alkene Hydroxylarylation/Lactonization

Here, we report the preparation of lactones via Ni-catalyzed alkene hydroxylarylation and sequential intramolecular lactonization with O₂ as a green oxidant and oxygen source. The bulky 1,3-diketone ligand is crucial by enabling Ni-catalyzed hydroxylarylation of alkenes, providing numerous phthalide and furanone derivatives with high efficiency under mild conditions. The synthetic value of this methodology was further demonstrated by the efficient synthesis of typhaphthalide and a monoamine oxidase B inhibitor.

期刊介绍： Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
