Boletopsins 7 (1), 11 (2), and 12 (3) are p-terphenyl dibenzofuran compounds, isolated from the Papua New Guinean medicinal mushroom Boletopsis sp. The first syntheses of these fungal metabolites are reported, allowing for an investigation of their antibiotic activity. The key steps include sequential Suzuki–Miyaura couplings to rapidly form the p-terphenyl backbone and an Ullmann ether synthesis on
Boletopsins 7(1),11(2)和12(3)是从巴布亚新几内亚药用蘑菇Boletopsis sp。分离的对-叔苯基二苯并呋喃化合物。报道了这些真菌代谢物的首次合成,可以对其抗菌活性进行研究。关键步骤包括顺序的Suzuki-Miyaura偶联,以快速形成对-叔苯基骨架,以及在甲酸酯上合成Ullmann醚以生成二苯并呋喃部分。针对一组细菌性医院病原体对合成化合物和中间体进行了生物学评估。
