Abstract
Abstract 4-Phenoxybut-1-ene undergoes both ortho and meta intramolecular photocycloaddition on 254 nm irradiation: in the latter process the addition is directed by the alkoxy tether to the arene 2,6-positions. Methyl substitution on the ethene and arene units does not affect the regiochemistry of the reaction but the presence of a 2′-methoxy group inhibits the meta process and only the ortho addition occurs.
