Simplified access: Substituted benzolactones can be obtained in one step by a Pd‐catalyzed ligand‐accelerated C(sp3)H bond‐activation/C(sp3)O bond‐formation protocol. This step‐economical approach enables the preparation of benzolactones with a wide variety of functional groups and different substitution patterns. The method is characterized by its simplicity and the avoidance of protecting groups
简化访问:取代的benzolactones可以在一个步骤通过Pd催化的
