A modified and efficient Knoevenagel condensation procedure was developed to synthesize the title compounds using β-alanine and acetic acid as catalysts, showing good to excellent yields. We used lawsone with suitable aliphatic aldehydes including isobutyraldehyde, 3-methylbutyraldehyde, 2-ethylbutyraldehyde, phenylacetaldehyde, 2-phenyl-propionaldehyde, among others. These compounds were submitted
开发了一种改进的有效的Knoevenagel缩合方法,以β-丙氨酸和乙酸为催化剂合成标题化合物,显示出良好或优异的收率。我们使用了具有适当脂族醛的Lawsone,其中脂族醛包括异丁醛,3-甲基丁醛,2-乙基丁醛,苯基乙醛,2-苯基丙醛等。这些化合物针对三种肿瘤细胞系进行了细胞毒性筛选,这些肿瘤细胞系表现出良好至优异的细胞毒性谱。
