A general synthetic procedure for the 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 ambient temperature Ullmann coupling. The subsequent McMurry condensation gave rise to the phenanthrene in 45-57% yields.
