An efficient method was developed for the synthesis of highly substitutednaphthalenes through rhodium‐catalyzed oxidative benzannulation of N‐pivaloylanilines with internal alkynes. The benzannulation reaction proceeded smoothly through dual C−H bond activation to produce the corresponding highly substitutednaphthalene products in satisfactory to good yields.
