preparation of polyoxygenated phenanthrenes from substituted derivatives of benzaldehyde is described. The key compound is a 6,6'-biphenyl-1,1'-dicarboxaldehyde intermediate formed through an ambienttemperatureUllmanncoupling. The subsequent McMurry condensation gave rise to the phenanthrene in 45-57% yields.
