A simple and efficient route for the synthesis of oxepine‐, oxocine‐, oxepinone‐, and dioxocine‐angularly annulated flavone skeletons has been developed. The combined Claisen rearrangement and the ring‐closing metathesis are used as key steps for the construction of C7/C8–C6–C6 tricyclic core structures.
已开发出一种简单有效的方法,用于合成奥西平,奥索辛,奥沙酮和二氧辛角成环的黄酮骨架。克莱森重排和闭环复分解相结合,是构建C 7 / C 8 –C 6 –C 6三环核结构的关键步骤。
