Axially chiral amides are usually found in many biologically active compounds and are useful ligands in asymmetric catalysis. Herein, by using the dynamic kinetic resolution approach, an asymmetric allylic alkylation reaction of racemic amide naphthols is disclosed, which leads to generation of the axially chiral naphthamides in good to excellent yields (up to 97%) and enantioselectivities (up to 96:4
轴向手性酰胺通常存在于许多生物活性化合物中,并且在不对称催化中是有用的配体。本文中,通过使用动态动力学拆分方法,揭示了外消旋酰胺萘的不对称烯丙基烷基化反应,其导致轴向手性萘酰胺的生成,具有良好的产率(高达97%)和对映选择性(高达96:4)。 er)。使用密度泛函理论来获得对该反应中对映选择性的理论理解。
