We describe a new total synthesis for 9-(2-dimethylaminoethylamino)-6-hydroxy-7-methoxybenzo-[g]isoquinoline-5,10-dione (1) via cyclization and amination. Compound 1 acts as a DNA intercalator and inhibitor of gyrase and mammalian topoisomerase I and II. Preparation of the precursor heterocycle 2a can be accompanied by the Hayashi rearrangement, which is studied by semiempirical methods (AM1, PM3)
我们描述了一种新的全合成的9-(2-二甲基氨基乙基氨基)-6-羟基-7-甲氧基苯并-[ g ]异喹啉-5,10-二酮(1)通过环化和胺化。化合物1充当DNA插入剂和回旋酶以及哺乳动物拓扑异构酶I和II的抑制剂。前体杂环2a的制备可以伴随Hayashi重排,通过半经验方法(AM1,PM3)对其进行研究。此外,通过异狄尔斯-阿尔德方法建立了取代苯并[ g ]异喹啉(例如,甲苯二cladin(3))的新的区域选择性途径。这些Diels–Alder反应的区域选择性是通过过渡态的半经验计算(AM1)预测的。
