AuCl3‐Catalyzed Ring‐Closing Carbonyl–Olefin Metathesis

Abstract Compared with the ripeness of olefin metathesis, exploration of the construction of carbon–carbon double bonds through the catalytic carbonyl–olefin metathesis reaction remains stagnant and has received scant attention. Herein, a highly efficient AuCl 3 ‐catalyzed intramolecular ring‐closing carbonyl–olefin metathesis reaction is described. This method features easily accessible starting materials, simple operation, good functional‐group tolerance and short reaction times, and provides the target cyclopentenes, polycycles, benzocarbocycles, and N‐heterocycle derivatives in good to excellent yields.
