arylation of quinoline-8-carbaldehydes with either aryl iodides or aryl diazonium salts for the synthesis of aryl quinolinyl ketones. Aryl iodide substituted with an electron-donating group favors the reaction, whereas aryl diazonium salt substituted with an electron-withdrawing group showed excellent reactivity. A range of aryl quinolinyl ketones were synthesized in good-to-excellent yields, with very good
我们开发了一种 Pd 催化的喹啉-8-甲醛与芳基碘化物或芳基重氮盐直接 C-H 芳基化的方法,用于合成芳基喹啉酮。被给电子基团取代的芳基碘有利于反应,而被吸电子基团取代的芳基重氮盐显示出优异的反应活性。一系列芳基喹啉基酮以良好到优异的收率合成,具有非常好的官能团耐受性。我们的方法已成功应用于合成高效微管蛋白聚合抑制剂,并且可以轻松放大至克级。
