Bauhinoxepin J possessing antimycobacterial, antimalarial, and tumor growth inhibitory activities was efficiently synthesized. The method involves crucial steps, including a coupling reaction of two aromatic moieties to construct the desired carbon framework, chemoselective phenol oxidation of a bisphenol derivative to establish a key cyclization precursor, and construction of a characteristic seven-membered
有效合成了具有抗分枝杆菌、抗疟和肿瘤生长抑制活性的 Bauhinoxepin J。该方法涉及关键步骤,包括两个芳族部分的偶联反应以构建所需的碳骨架,双酚衍生物的化学选择性苯酚氧化以建立关键的环化前体,以及通过内部环化构建特征性的七元二氢氧杂环己酮环以产生靶标 bauhinoxepin J。
