Pd(II)-catalyzed g-G(sp3)-H arylation or heteroarylation 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, swift synthesis of 1,2,3,4-tetrahydronaphthyridine derivatives is accomplished using this reaction.
利用 2-hydroxynicotinaldehyde 作为催化瞬时指导基团,实现了 Pd(II) 催化 g-G(sp3)-H芳基化或伯胺杂芳基化。重要的是,催化剂和引导基的负载量可分别降低到 2% 和 4%,从而证明了这种新设计的瞬时引导基的高效性。杂环芳基碘化物也与该反应兼容。此外,利用该反应还能快速合成 1,2,3,4-四氢萘啶衍生物。
