  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.

  The Buchwald–Hartwig coupling/Michael addition sequence has been successfully applied to the synthesis of functionalized 1,2-disubstituted 4-quinolones using Pd(OAc)2 as a catalyst and PPh3 as a ligand. Under these conditions, the intermediate products first formed from chalcones and primary amines underwent catalytic dehydrogenation to yield the 1,2-disubstituted 4-quinolones.

  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。

  A highly efficient palladium-catalyzed asymmetric synthesis of N-substituted 4-quinolones was developed via C−N coupling reaction. Various chiral quinolones were readily obtained with desirable enantioselectivity (up to 95% ee) and excellent yield (up to 99%), enabled by a simple system of palladium acetate and chiral ferrocene bisphosphine as auxiliary ligand. The corresponding racemic derivatives

  通过 C-N 偶联反应开发了一种高效钯催化的N-取代 4-喹诺酮不对称合成。通过醋酸钯和手性二茂铁双膦作为辅助配体的简单系统，可以很容易地获得各种具有理想对映选择性（高达 95% ee）和出色收率（高达 99%）的手性喹诺酮类化合物。相应的外消旋衍生物也可以通过氢氧化钾在 DMSO 中的无过渡金属策略合成。还研究了温度对这些 C−N 轴向手性化合物构型稳定性的影响。三位高效功能化进一步扩展了该合成技术的应用范围。
