1,4-Naphthoquinone 1-oxime methyl ethers carrying an ester-substituted aryl pendant at 2-position were concisely prepared as seed compounds with structural flexibility for structure–activity relationship studies on antitumor activity. The key synthetic intermediate was a phthalide–tetralone spiro compound, which was provided by palladium-coupling reaction between 2-bromobenzoate and 1-tetralone followed
在 2 位带有酯取代芳基侧链的 1,4-萘醌 1-肟甲基醚被简明地制备为具有结构灵活性的种子化合物,用于抗肿瘤活性的构效关系研究。关键的合成中间体是苯酞-四氢萘酮螺环化合物,它是通过 2-溴苯甲酸酯和 1-四氢萘酮之间的钯偶联反应,然后是 OsO4-NMO 氧化提供的。
