Dearomatization of an indole via palladium(0)-catalyzed cross-coupling reaction has been realized. With readily available triphenylphosphine as ligand, various spiroindolenine derivatives have been obtained in good to excellent yields, and enantioselective control is also feasible with chiral ligands.

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
