Weak coordination is powerful! A PdII‐catalyzed olefination of ortho‐CH bonds of arenes directed by weakly coordinating ethers is developed by using monoprotectedaminoacid (MPAA) ligands. This finding provides a method for chemically modifying ethers, which are abundant in natural products and drug molecules. HFIP=hexafluoroisopropanol.
弱协调能力强!通过使用单保护氨基酸 (MPAA) 配体,开发了由弱配位醚引导的Pd II催化芳烃邻位C H 键的烯化反应。这一发现提供了一种对醚进行化学修饰的方法,醚在天然产物和药物分子中含量丰富。HFIP=六氟异丙醇。
