the synthesis of linear tetraenes to initiate a biosynthetic 8π/6π-electrocyclization cascade. This work forges a functionalized bicyclo[4.2.0]octadiene in two steps from cyclooctatetraene. The versatility of this method is demonstrated through natural product synthesis, including the first totalsynthesis of kingianic acid A and formal syntheses of kingianins A, D, and F and cryptobeilic acid D ethyl
双环[4.2.0]辛二烯天然产物的合成方法经常使用线性四烯的合成来启动生物合成的8π/6π-电环化级联。这项工作从环辛四烯分两步锻造功能化的双环[4.2.0]辛二烯。该方法的多功能性通过天然产物合成得到证实,包括首次全合成金刚烷酸 A 以及金刚烷素 A、D 和 F 和隐贝酸 D 乙酯的正式合成。通过密度泛函理论建模使E、E、Z、E -四烯副产物的意外形成合理化。
