(Figure Presented) An exceedingly sterically demanding, rigid, and chiral NHC ligand, IBiox[(-)-menthyl] (1), was prepared and structurally characterized. With a buried volume of 50percent, this ligand arguably represents one of the most sterically demanding monodentate ligands. The ability to use aryl chloride substrates in intramolecular palladium-catalyzed ,-arylations reveals its unique reactivity. Moreover, C2-symmetric 1 allows the highly enantioselective formation of oxindoles withup to 99percent ee.
