Abstract An enantioselective copper‐catalyzed intramolecular borylacylation is reported. The reaction proceeds through an initial enantioselective borylcupration of the styrene, followed by a nucleophilic attack on the tethered carbamoyl chloride. The products, chiral borylated 3,3‐disubstituted oxindoles, were generated in excellent yields and enantioselectivities. The versatile carbon–boron bond provides a platform for a wide array of diversification.
