A highly efficient method for the copper-catalyzed asymmetric allylicalkylation of ortho-substituted cinnamyl bromides with Grignard reagents is reported. The use of a catalytic system comprising CuBr·SMe2 and TaniaPhos as chiral ligands gives rise to a range of branched products with excellent regio- and enantioselectivity.
