A newmethod was developed for the photoinduced dearomatization of arenes through an intramolecular cycloaddition with aza‐o‐xylylenes generated by excited‐state intramolecular proton transfer (ESIPT) in the readily available photoprecursors. The [2+4] topology of this cycloaddition is unprecedented for photo‐dearomatizations of benzenoid aromatic carbocycles. It provides rapid access to novel heterocycles
