我们报道了我们通过Suzuki偶联、分子内环丙烷化和关键的二乙烯基环丙烷重排反应,以发散的方式全合成姜黄酮A-D的迭代努力。我们的合成进展受到高度底物依赖的环丙烷化步骤的反复挑战,我们最终可以通过明智地选择六元环片段上的取代基来克服这一点。
We report our iterative efforts toward the divergent total syntheses of curcusones A–D via Suzuki coupling, intramolecular cyclopropanation, and a key divinylcyclopropane rearrangement. Progress of our synthesis was repeatedly challenged by the highly substrate-dependent cyclopropanation step, which we could ultimately overcome by judicious choice of substituents on the six-membered ring fragment.
