    • Abstract


      The formation of isomers from the inter- and intra-molecularmeta photocycloaddition of ethenes to the benzene ring has been specifically directed using the addend substituents in order to cause an asymmetric distortion of theC6 ring during the reaction, and to induce non-synchroneity into the addition process. The latter influence in the intramolecular reaction is achieved by the presence of a heteroatom in the linking tether which also provides a convenient access to linear and angular heterotriquinanes. Themeta photoaddition can be induced by sunlight exposure of appropriately substituted arene-ethene bichromophores.
