An efficient protocol has been developed for the intramolecularoxidativeoxyarylation using a PdII‐catalyzed tandem oxypalladation/CHfunctionalization strategy. This methodology allows rapid access to tetrahydro‐2H‐indeno‐[2,1‐b]furan frameworks from simple hydroxyalkenes. The reactivity of this process is orthogonal to that of Pd0‐catalyzed transformations, enabling the divergent modification of
使用 Pd II催化的串联氧钯化/C H 功能化策略开发了一种有效的分子内氧化氧基化方案。该方法允许从简单的羟基烯烃快速获得四氢-2H-茚并- [2,1- b ]呋喃骨架。该过程的反应性与 Pd 0催化转化的反应性正交,从而能够对单个分子进行不同的修饰。
