通过Suzuki偶联反应完成了Cochlearol F和Didehydroconicol的全合成。该合成的创新点为使用了联苯硼酸。Cochlearol F的全合成中,关键反应为联苯硼酸与烯醇三氟甲磺酸酯的偶联构建新的碳碳键,共需4步,总收率为25%;在后者的全合成中,关键反应为联苯硼酸的一氧化碳插入形成联苯内酯,共需7步,总收率为23%;本合成策略将为含联苯结构的天然产物的合成提供参考.

Total syntheses of Cochlearol F and Didehydroconicol were accomplished through the Suzuki coupling reaction, with the innovative use of biphenylboronic acid. In the total synthesis of Cochlearol F, the key reaction involved the coupling of biphenylboronic acid with enol trifluoromethanesulfonate to construct a new carbon-carbon bond, requiring four steps in total, with an overall yield of 25%. In the total synthesis of Didehydroconicol, the key reaction was the insertion of carbon monoxide into biphenylboronic acid to form a biphenyl lactone, requiring seven steps in total, with an overall yield of 23%. This synthetic strategy will provide a reference for the synthesis of natural products containing biphenyl unit.
