Asymmetric annulation via palladium-carbene intermediates offers a powerful route to chiral cyclic frameworks, yet its development remains a significant challenge. Here, a Pd-catalyzed asymmetric [4+1] annulation for constructing chiral indanes is disclosed, enabled by a novel dynamic multiligand relay asymmetric catalysis. The ligand relay system employs a bidentate Pyrox ligand to promote the oxidative addition, while a monodentate Feringa-type phosphoramidite ligand facilitates the carbenation/migratory insertion step and the following intramolecular Tsuji-Trost reaction. The practical utility of this method was confirmed through a scale-up experiment. This strategy establishes a practical and efficient route to enantioenriched vicinal substituted indanes.
