A whole lot o' metal: An efficient copper‐catalyzed asymmetric conjugate addition was achieved using a binol‐derived ligand. The catalytic system has a turnover number of 2000, and the excellent catalytic performance could be attributed to the generation of a multinuclear complex such as 1. binol=2,2′‐dihydroxy‐1,1′‐binaphthyl.
