The first Mannich reaction employing phthalides using a quinidine-based multifunctional catalyst has been developed. The reported method led to the synthesis of 3,3-disubstituted phthalide derivatives in excellent yields, with good diastereo- and enantioselectivities. Convenient synthesis of chiral isoquinolinones and isoquinolines has also been demonstrated.
首次利用基于奎尼丁的多功能催化剂进行邻苯二甲酸内酯的Mannich反应已被开发。所报道的方法合成了3,3-二取代的邻苯二甲酸内酯衍生物,产率极高,且具有良好的非对映选择性和对映选择性。此外,便捷合成手性异喹啉酮和异喹啉的示例也已得到证明。
