Intramoleculararomaticsubstitution and Büchner reaction have been established as powerful methods for the construction of polycyclic compounds. These reactions are traditionally catalyzed by RhII catalysts with α‐diazocarbonyl compounds as the substrates. Herein a transition‐metal‐free intramoleculararomaticsubstitution/Büchner reaction is presented. These reactions use readily available N‐tosylhydrazones
