A highly enantioselective copper‐catalyzed vinylogous propargylic substitution has been developed. Aromatic and aliphatic propargylic esters react smoothly with substituted coumarins under mild reactionconditions to give the desired products with excellent yields and enantioselectivities. Subsequent single‐step transformations enable the synthesis of a wide range of multifunctional and diverse compounds
