While numerous cyclophanes exist in which heteroaromatic nuclei (e.g. furan,2-5 thiophene, 296 pyridine 6-8 ) are incorporated into the cyclophane macrocycle, those which contain the pyrrole moiety' are conspicuously absent from these ranks. Recently, we reported the synthesis of a number of cycloph

Novel 1,8-naphthylene-bridged paraand metacyclophanes were efficiently synthesized as a single isomer by the intramolecular [2 + 21 photocycloaddition of 1,8-bis(p-and m-vinylphenyl)naphthalenes, respectively. By this method, syn-cyclophanes were selectively obtained in both cases.
