Abstract
Abstract The photochemical reactions of 4-methoxy-1-naphthonitrile ( 1 ) and 2-methoxy-1-naphthonitrile ( 2 ) with acrylonitrile ( 3 ) and 3,4-dihydro-2H-pyran ( 4 ) in ethyl acetate solution were studied. Irradiation of 1 with 3 and 4 gives the 1( endo ),8b-dicyano-4-methoxy-1,2,2a-trihydrocyclobuta[a]naphthalene 5 and the cyclobutane adduct 6 respectively. Irradiation of 2 with 3 and 4 gives the 1( endo ),8b-dicyano-2a-methoxy-1,2-dihydrocyclobuta[a]-naphthalene 7 and the cyclobutane adduct 8 respectively. The irradiations were carried out using a medium pressure mercury arc lamp or sunlight.
