Herein we present a facile four-step synthetic method for the synthesis of novel 2-aryl-substituted 7,8-dihydroquinolin-6(5H)-ones as cytotoxic agents. The key step was the use of Mannich salts derived from acetophenones as a Michael acceptor in the reaction with cyclohexane-1,4-dione monoethylene acetal to give 1,5-dicarbonyl compounds that were treated with ammonium acetate to give the 7,8-dihydroquinolin-6(5H)-ones. The cytotoxic activity of the synthesized compounds was evaluated against seven cell lines. The observed data showed good selectivity for chronic myeloid leukemia line K-562. The synthetic route was simple and applicable to various functional group containing substrates. These types of compounds may be utilized as lead compounds in cancer research and drug discovery.

在此，我们提出了一种简便的四步合成方法，用于合成新型2-芳基取代的7,8-二氢喹啉-6(5 H )-酮作为细胞毒剂。关键步骤是使用苯乙酮衍生的曼尼希盐作为迈克尔受体，与环己烷-1,4-二酮单乙烯缩醛反应，得到1,5-二羰基化合物，用乙酸铵处理，得到7,8-二羰基化合物。二氢喹啉-6(5 H )-酮。针对七种细胞系评估了合成化合物的细胞毒活性。观察数据显示对慢性粒细胞白血病株K-562具有良好的选择性。该合成路线简单，适用于各种含官能团的底物。这些类型的化合物可用作癌症研究和药物发现中的先导化合物。
