realized by using copper catalysts modified with chiral spirobisoxazoline ligands, which provides a novel strategy for the synthesis of chiral 2‐carboxytetrahydroquinolines. This reaction features fast reaction rate, high yield, high enantioselectivity, and mild reaction conditions.
通过使用经手性螺双二恶唑啉配体改性的铜催化剂,实现了第一个高度对映选择性的分子内NH键插入,这为手性2-羧基四氢喹啉的合成提供了新的策略。该反应具有反应速度快,产率高,对映选择性高和反应条件温和的特点。
