  Synthesis of N-Alkyl-Substituted 4-Quinolones via Tandem Alkenyl and Aryl C-N Bond Formation

  摘要：

  N-Alkyl-substituted 4-quinolones are present as the key structural motif in many marketed drugs. An efficient one-step tandem amination approach was developed to afford N-alkyl-substituted 4-quinolones in high yields from easily accessible o-chloroaryl acetylenic ketones and functionalized alkyl amines. The approach complements and extends our previous work. Compared with other reported methods, the current method provides a very simple and convenient route.

  and direct approach for constructing 4-quinolones from simple and readily available anilines and alkynes is described. Under the optimal conditions, both N-alkyl- and N-aryl-substituted anilines can be successfully transformed into the corresponding 4-quinolones. This reaction is characterized by mild reaction conditions, high functional-group tolerance, and amenability to gram-scale synthesis.

  were transformed into quinolin-4(1H)-one products by a palladium-catalyzed intramolecular N-arylation in a tandem one-pot manner, with good to excellent yields. A convenient approach has been developed for the construction of quinolin-4(1H)-one frameworks, starting from (Z)-β-chlorovinyl aromatic ketones and amines. Intermolecular Michael addition of an amine to a (Z)-β-chlorovinyl ketone was followed

  摘要 从（Z）-β-氯乙烯基芳族酮和胺开始，已经开发了一种方便的方法来构建喹啉4（1 H）-one骨架。在（Z）-β-氯乙烯基酮的分子间迈克尔加成胺之后，消除氯离子，得到烯胺中间体，并完全保留了初始Z-构型。通过钯催化的分子内N-芳基化以串联-一锅方式将烯胺中间体转化为喹啉-4（1 H）-一产物，具有良好的优良的收率。 从（Z）-β-氯乙烯基芳族酮和胺开始，已经开发了一种方便的方法来构建喹啉4（1 H）-one骨架。在（Z）-β-氯乙烯基酮的分子间迈克尔加成胺之后，消除氯离子，得到烯胺中间体，并完全保留了初始Z-构型。通过钯催化的分子内N-芳基化以串联-一锅方式将烯胺中间体转化为喹啉-4（1 H）-一产物，具有良好的优良的收率。
