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.

Unsaturated oxoesters and amides have been submitted to cross-coupling metathesis with trimethylallylsilane using Grubbs' catalyst. The resulting allylsilanes underwent, under irradiation, intramolecular [2+2] photocycloaddition leading to trimethylsilylmethylcyclobutanes. By treatment with an appro
