Catalytic enantioselective radical conjugateaddition reactions using alpha'-phosphoric enone templates have been studied. The C 2-symmetric bisoxazoline-zinc(II) complex proves to be effective for high enantioselectivities and chemical yields. In addition, intermediate alpha-carbonyl alkyl radicals could be trapped with allyltributylstannane to afford anti-isomers as major products with high enantioselectivities
