A novel and practical preparation of 2-pyridone-containing tricyclic alkaloid derivatives was developed. By regioselective intramolecular N- and C-acylation of 2-(4-aryl-2-pyridon-6-yl)benzoic acid, a pair of structural isomers 2-aryl pyrido[2,1-a]isoindole-4,6-diones and 4-aryl 1-methyl-1H-indeno[1,2-b]-pyridine-2,5-diones, as potential inhibitors of tumor cell proliferation, were prepared respectively.
本研究开发了一种新颖实用的含 2-吡啶酮的三环生物碱衍生物的制备方法。通过对 2-(4-芳基-2-吡啶-6-基)苯甲酸进行区域选择性分子内 N-和 C-酰化,分别制备了一对结构异构体 2-芳基吡啶并[2,1-a]异吲哚-4,6-二酮和 4-芳基 1-甲基-1H-茚并[1,2-b]-吡啶-2,5-二酮,它们是潜在的肿瘤细胞增殖抑制剂。
