developed. It offers a straightforward and atom-economical protocol for the synthesis of functionalized (E,E)-1,6-dioxo-2,4-diene derivatives in moderate to good yields with excellent stereo- and chemoselectivities. In addition, the synthetic utility of this method was further demonstrated by its application to the synthesis of bioactive natural products such as (7E,9E)-henicosa-7,9-diene-6,11-dione (sex
开发了一种Ru催化的乙烯基酮直接氧化偶联反应。它提供了一种直接且原子经济的方案,用于以中等至良好的收率合成功能化的 ( E , E )-1,6-dioxo-2,4-二烯衍生物,并具有出色的立体选择性和化学选择性。此外,该方法在合成生物活性天然产物如 (7 E ,9 E )-henicosa-7,9-diene-6,11-dione (性信息素)中的应用进一步证明了该方法的合成效用, ostopanic acid(植物抗癌剂)、JA(抗肿瘤剂)和抗生素macrolactin-T的南部(C1-C13)。
