straightforward palladium-catalyzed process exploits a distinct reaction pathway, wherein a sterically hindered carboxylate ligand orchestrates an amine attack on a palladium anhydride to transform aliphatic amines into β-lactams. The reaction is successful with a wide range of secondary amines and can be used as a late-stage functionalization tactic to deliver advanced, highlyfunctionalized amine products
CO 率先制造 β-内酰胺环 应变的 β-内酰胺环是青霉素和其他一些药物的关键特征。威尔考克斯等人。通过一氧化碳与仲胺的钯催化偶联,设计了一条通向这些四元环基序的通用途径。庞大的羧酸盐配体似乎有助于将 CO 初步掺入 Pd 酐中,然后通过 C-H 活化被胺攻击以建立闭环。与之前的 C-H 活化先于 CO 插入的方案相比,这种方法拓宽了底物范围。科学,这个问题 p。851 庞大的羧酸盐配体引导钯将一氧化碳和仲胺偶联成用于药物研究的多功能基序。胺的合成和功能化方法对于各种化学应用具有本质的重要性。我们提出了一种通用的碳氢键活化过程,该过程结合了现成的脂肪胺和原料气一氧化碳,以形成合成通用的增值酰胺产品。操作简单的钯催化过程利用了独特的反应途径,其中空间位阻的羧酸盐配体协调对钯酐的胺攻击,将脂肪胺转化为 β-内酰胺。该反应可成功用于多种仲胺,并可用作后期官能化策略,以提供可用于药物研究和其他领域
