title: Highly enantioselective [4 + 2] cycloaddition of allenoates and 2-olefinic benzofuran-3-ones.
abstract: A highly enantioselective [4 + 2] cycloaddition of allenoates with 2-olefinic benzofuran-3-ones catalyzed by (DHQD)2AQN, which allowed the synthesis of optically active dihydropyran-fused benzofurans, was developed.
