A simple and efficient route for the synthesis of oxepine‐, oxocine‐, oxepinone‐, and dioxocine‐angularly annulated flavone skeletons has been developed. The combined Claisen rearrangemen t and the ring‐closing metathesis are used as key steps for the construction of C 7 /C 8 –C 6 –C 6 tricyclic core structures.
