A convenient one-pot synthesis of 2,3-disubstituted, 2,3,6-trisubstituted, and 2,3,6,7-tetrasubstituted quinoline analogues from terminal alkynes via sequential ruthenium(II) and para-toluenesulfonic acid (p-TSA) co-catalyzed reactions is described. The catalytic process is shown to take place first via intermediate formation of an allyl ketone and then addition of an aniline derivative to the allyl
的一种方便的一锅合成2,3-二取代的,2,3,6-三取代的,和从末端炔2,3,6,7-四取代的喹啉类似物通过连续钌(II)和对甲苯磺酸(p -描述了TSA)共催化的反应。显示出催化过程首先通过中间形成烯丙基酮,然后将苯胺衍生物加到烯丙基酮中而发生。该p -tsa对于两个烯丙基酮和喹啉的合成步骤的催化剂。该方法使我们能够合成各种喹啉衍生物,并通过使用各种简单的起始原料引入不同的取代基。该反应允许合成含卤素的产物。
