A copper‐catalyzed enantioselective Claisenrearrangement of easily accessible enolphosphonates using the commercially available PhBOX as the chiral ligand was developed. A wide range of rearrangement products with contiguous tertiary and all‐carbon quaternarycenters were obtained in excellent yields and stereoselectivities. The α‐ketophosphonate substituent in the products could be easily transformed
