heterocycles are found widely in biologically active compounds such as medicinal drugs and agrochemicals. However, boronic acid‐derived buildingblocks for these structures have limited availability, particularly in comparison to heteroaromatic boronic acids. We report the preparation of boronicester γ‐lactams through a Cu‐catalysed conjugate borylation‐cyclisation protocol. Using a chiral catalyst, this can
