Benzene is unreactive as a photochemistry partner with 2-pyridone, however benzene substitution can allow for an efficient [4+4] (a k a, ‘para’) photocycloaddition. Productive substituents include alkoxy, cyano, ester, and trifluoromethyl, suggesting that inductively electron-withdrawing groups are sufficient, however a single fluorine substituent does not result in cycloaddition. When the product
Enyne [4+4] Cycloaddition/Oxidation: Ring Contraction via Cyclopropanones and Their Anionic Ring-Opening Reactions

Irradiation of a 1,3‐enyne tethered to a 2‐pyridone, in the presence of oxygen, leads to formation of a seven‐membered ring product, an overall [4+4−1] reaction. This transformation involves two unstable intermediates and a sequence of unusual reactions. An initial [4+4] photocycloaddition of the enyne with the pyridone yields a 1,2,5‐cyclooctatriene. Photooxidation of this triene forms a cyclopropanone
Formation and isomerization of polycyclic 1,5-enynes

A 1,5-enyne with the alkyne flanked by a cyclopropane and a cyclobutane, formed by intramolecular [2+2] photocycloaddition of a pyridone with an enyne, undergoes gold catalyzed ring closure to give a cyclopentene, without isomerization of either small ring. The ring closure can also be effected by thiol radical conditions. The chemistry of the resulting tetracycle with its five stereogenic centers
