Metal-promoted asymmetric catalysis has proven to be an efficient method in carbon–carbon bond-forming reactions to obtain optically enriched compounds. Allylic substitution has attracted much attention and great effort has been put into controlling the chemo-, regio-, and enantioselective outcome of the reaction.[1] Extensive accounts report a wide variety of metals that use soft nucleophiles for the reaction (Pd, Ir, Mo, Rh, Ru).[2] In contrast, copper ...
