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.
摘要
开发了一种由（DHQD）2AQN催化的丙二烯酸酯与2-烯烃基苯并呋喃-3-酮的高度对映选择性[4 + 2]环加成反应，该反应可用于合成光学活性的二氢吡喃并苯并呋喃。
