Pd-catalyzed asymmetric dearomative arylation of C3-substituted indoles is realized via a desymmetrization strategy. A BINOL-derived chiral phosphoramidite ligand is found to be highly efficient for the stereoselective control in this reaction. This method provides a convenient synthesis of spiroindolenines bearing two stereogenic centers in good yields (up to 98%) with excellent diastereo- and enantioselectivities
