In this study, we developed an efficient and general synthetic strategy for thiaphenalene, a sulfur-containing polyaromatic heterocycle, and applied for the synthesis of 1-thio derivatives of mansonone I and F, natural 1-oxaphenalenic orthoquinones. The pivotal steps for the construction of thiophenalene skeleton include formation of arylsulfide by Newman–Kwart rearrangement of thiocarbamate or palladium-catalyzed cross-coupling, and pericyclic ring closure. Three bioisosterically modified orthoquinones were synthesized and were evaluated for anti-MRSA activity.
在这项研究中,我们为噻吩并苯,一种含硫的多环芳烃杂环,开发了一种高效且通用的合成策略,并应用于天然1-氧杂苯并苯醌的1-硫代衍生物曼松酮I和F的合成。构建噻吩并苯骨架的关键步骤包括通过Newman-Kwart重排噻吩甲酸盐或钯催化的交叉偶联形成芳基硫化物,以及周环闭环。合成了三种生物等排修饰的邻醌,并对其抗MRSA活性进行了评估。
