aldehydes has been achieved through a novel synergistic organocatalysis. The HOAc‐ activated 2‐methylquiolines undergo a Michael addition to 1,3‐dimethylbarbituric acid‐activated aldehydes, followed by a retro‐Michael addition to release 1,3‐dimethylbarbituric acid and the target products. The transformation produced various 2‐alkenylquinolines with good to excellent yields and featured mild reaction conditions
通过新型的协同有机催化,已经实现了
2-甲基喹啉与醛的有效,实用的直接烯基化反应。HOAc活化的
2-甲基喹啉在
1,3-二甲基巴比妥酸活化的醛中进行迈克尔加成反应,然后在Michael逆向加成反应中释放
1,3-二甲基巴比妥酸和目标产物。该转化产生了各种2-烯基
喹啉,具有良好或优异的收率,并且具有温和的反应条件,原子和阶梯经济,良好的官能团耐受性和操作简便性。
