A novel Pd‐catalyzed method for the synthesis of various naphtho[1,2‐b]furans is described. The sequential procedure involves Pd0‐catalyzed allenylation, 6π‐electrocyclization and 1,3‐H migration process. Wide substrate scope with easily accessible starting materials and good functional group tolerance indicate that this protocol may provide a general approach to those important frameworks.
