Synthesis of Diverse Oxa-Carbocycle-Annulated Flavones Using the Combined Claisen Rearrangement and Ring-Closing Metathesis

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–C6tricyclic core structures.
