simply that the addition of Pd(OAc)2 as a promotor switches the reactivity of a commonly used base NaH to a nucleophilic reductant. The reactivity is engineered into a palladium-catalyzed reductive debenzylation and deallylation of aryl ethers and esters. This operationally simple, mild protocol displays a broad substrate scope and a broad spectrum of functional group tolerance (>50 examples) and high chemoselectivity
在这里,我们简单地证明,添加Pd(OAc)2作为
促进剂会将常用的碱式NaH的反应性切换为亲核还原剂。反应性被设计成
钯催化的芳基醚和酯的还原性脱苄基作用和脱甲酰化作用。该操作简单,温和的方案显示了广泛的底物范围和宽泛的官能团耐受性(> 50个实例),并且对脂族结构上的芳基醚具有高
化学选择性。此外,在有效的合成工艺中证明了NaH作为碱和还原剂的双重反应性。
