• 2-Cyano-1,2-dihydrocyclobuta[a]naphthalene was synthesized from 2-methoxynaphthalene via photoaddition to acryionitrile followed by base treatment. The 4+2 cycioaddition of this compound to a variety of olefins by an application of the so-called benzocyclobutene method was examined and the regioselectivity and electron demand in these reactions were clarified. Construction of 12,13,14,15,16,17-hexahydro-11H-cyclopenta[a]phenanthrene derivatives having a basic A,B-ring-aromatized steroid skeleton from this naphthocyclobutene through either interorintramolecular 4+2 cycloaddition is also reported.
