A facile palladium‐catalyzed cascade carbonylation/Heck reaction/esterification has been developed. A large variety of alcohols and phenols were all tolerated well to access a series of benzofuran‐3(2 H )‐one‐containing γ‐ketoesters in moderate to good yields, broadening the application of carbonylation. The current research exhibits broad substrate scope, good functional‐group compatibility and straightforward scale‐up.
