Abstract In this article β-enaminonitrile 1 undergoes intramolecular cyclocondensation reaction under acidic conditions to generate novel chromeno[2,3-b]azet-9-one derivative 2 in good yield. Ring expansion of the four membered ring of the azet-2(1H)-one derivative 2 to six and/or seven membered rings was achieved via reaction of compound 2 with different nitrogen nucleophiles. A new series of benzochromeneone
摘要 在本文中,β-烯腈1在酸性条件下进行分子内环缩合反应,以高收率生成新的chromeno [2,3-b] azet-9-one衍生物2。通过化合物2与不同的氮亲核试剂反应,将azet-2(1H)-一衍生物2的四元环扩环成六个和/或七个元环。通过β-烯氨基腈1的反应制备了一系列新的苯并色酮,苯并色嘧啶和苯并[ f ]香豆素衍生物。具有不同的C-亲电试剂 根据分析和光谱数据确定了产品的结构。新合成的化合物对两种人上皮细胞系的抗增殖活性;除了正常的成纤维细胞(WI-38)外,还研究了肝脏(HepG2)和乳房(MCF-7)。衍生物4和10在不损害正常成纤维细胞的情况下,具有针对肝细胞和乳腺癌细胞系的显着且选择性的抗增殖活性。 图形摘要
