straightforward procedure for the synthesis of 3-arylquinolin-2(1H)-ones has been developed. The synthesis proceeds through a palladium-catalyzed reductive aminocarbonylation reaction of benzylic ammonium triflates with o-nitrobenzaldehydes, and a wide range of 3-arylquinolin-2(1H)-ones was obtained in moderate to good yields with very good functional group compatibility.
已开发出一种钯催化的直接合成 3-芳基喹啉-2(1 H )-酮的方法。该合成通过苄基三氟甲磺酸铵与邻硝基苯甲醛的钯催化还原氨基羰基化反应进行,并以中等至良好的收率获得了范围广泛的 3-芳基喹啉-2(1 H)-酮,并具有非常好的官能团兼容性。
