Intramolecular alkene-arene meta-photocycloaddition reactions are powerful ‘reagentless’ transformations that form complex three-dimensional fused-ring systems from readily accessible starting materials. By judicious tether design in combination with continuous flow it is demonstrated that substrates with a four-membered tether can also undergo meta-photocycloaddition in good yield, enabling access
