[摘要]:Catalytic enantioselective radical conjugate addn. reactions using a'-phosphoric enone templates have been studied. The C2-sym. bisoxazoline-zinc(II) complex proves to be effective for high enantioselectivities and chem. yields. In addn., intermediate a-carbonyl alkyl radicals could be trapped with allyltributylstannane to afford anti-isomers as major products with high enantioselectivities. |
