A practical copper-catalyzed highly regioselective 1,2-hydrocarboxylation of terminal 1,3-diene with carbon dioxide has been developed. Under mild reaction conditions, this chemistry afforded 2-benzyl-β,γ-unsaturated acid derivatives as products, which are a kind of important unit for bio-active molecules and versatile precursors for organic synthesis, with good functional group tolerance. The key
已经开发出实用的铜催化的末端1,3-二烯与二氧化碳的高度区域选择性的1,2-氢羧化。在温和的反应条件下,该化学方法得到了2-苄基-β,γ-不饱和酸衍生物,该衍生物是生物活性分子的重要单元和有机合成的通用前体,具有良好的官能团耐受性。对照实验说明了该转化过程中的关键中间体。
