摘要
We report here a palladium-catalyzed enantioselective synthesis of indole-based atropisomers via an intramolecular dynamic kinetic C-H cyclization. The TADDOL-derived phosphoramidite ligand proves to be most efficient in this directing-group-free transformation, delivering products with up to 96:4 er. The thermal stability of the axial chirality of the atropisomers has also been investigated.
