Irradiation of a wet acetonitrile nitrile solution of 1,1-diphenyl-1,6-heptadiene in the presence of 1,4-dicyanobenzene and phenanthrene provided cis-1-acetamido-3-(diphenylmethyl)cyclohexane in high yields with high stereoselectivity. Several examples leading to cis-1-acylamino-3-diphenylmethyl)cyclohexanes were also described.
Phenanthrene-sensitized photoreaction of 1,1-diphenylethene (DPE) derivatives and 1,4-dicyanobenzene (DCNB) in benzene leads to a novel intermolecular cycloaddition to give isoquinoline derivatives as a novel synthetic method. The feasibility of this reaction was dependent upon the side chain structure of DPE derivatives, which would regulate the stability of radical cation DPE+· in a highly polar
