Alkenyl cyclopropyl ketones tethered to (hetero)arenes readily underwent catalytic, intramolecular interrupted homo-Nazarov cascade biscyclizations to form 6,6,6-, 6,5,6-, 6,6,5-, 6,6,6,5-, and 6,6,5,6-fused angular architectures. The approach was used for the concise total synthesis of (±)-1-oxoferruginol, a bioactive abietane diterpenoid.
连接到(杂)芳烃上的烯基环丙基酮很容易经历催化、分子内中断的同-纳扎罗夫级联双环化,形成 6,6,6-、6,5,6-、6,6,5-、6,6,6,5 - 和 6,6,5,6 融合的角度架构。该方法用于 (±)-1-oxoferruginol 的简明全合成,这是一种具有生物活性的枞树烷二萜。
