Pd(II)-catalyzed γ-C(sp3)-H arylation of primary amines is realized by using 2-hydroxynicotinaldehyde as a catalytic transient directing group. Importantly, the catalyst and the directing group loading can be lowered to 2% and 4% respectively, thus demonstrating high efficiency of this newly designed transient directing group. Heterocyclic aryl iodides are also compatible with this reaction. Furthermore
Pd(II)-催化的伯胺的γ-C(sp3)-H芳基化是通过使用2-羟基烟醛作为催化瞬态导向基团来实现的。重要的是,催化剂和导向基团的负载量可以分别降低到 2% 和 4%,从而证明了这种新设计的瞬态导向基团的高效率。杂环芳基碘化物也与该反应相容。此外,使用该反应可以快速合成 1,2,3,4-四氢萘啶衍生物。
