A highly stereoselective asymmetric Henry reaction using a double fluorous-tagged Co–salen complex was conducted. The introduction of two fluorous tags into the Co–salen complex was found to be more effective in terms of improving stereoselectivity than the introduction of a strong electron-withdrawing nitro group into the same position of the salen ligand. The observed stereoselectivity was significantly
使用双氟标记的 Co-salen 复合物进行了高度立体选择性的不对称亨利反应。发现在 Co-salen 配合物中引入两个含氟标签在提高立体选择性方面比在salen 配体的相同位置引入强吸电子硝基更有效。观察到的立体选择性显着高于使用具有相同不对称源的 Jacobsen 型 Co-salen 络合物时的立体选择性。
