The discovery of atropisomers with unique skeletal structures is important for the development of chiral catalysts, ligands, drugs, and materials. Herein, we report the development of palladium-catalyzed enantioselective domino cyclization chemistry for generating tetra-substituted methylene oxindole atropisomers. A set of rarely reported oxindole–indole atropisomers was synthesized in high yields
