Novel 1, 3-Dipolar Cycloadditions of Cyclobutene Diester Epoxides to Polycyclic Aromatic Hydrocarbons

This paper announces the results of certain 1, 3-dipolar cycloadditions to polycyclic aromatic hydrocarbons (PAHs). The 1, 3-dipoles generated from cyclobutene diester epoxides thermally reacted with PAHs to give cycloadducts. This reaction demonstrated the remarkable ability of these 1, 3-dipoles to disrupt an aromatic system by adding across specific ‘ aromatic double bonds’ . Similar products were prepared by “ cross” oxadiazole (OD) coupling yielding the same geometry and stereochemistry as the cyclobutene diester epoxide derived products, but in inferior yields.
