Abstract[2+2+1] iron and cobalt mediated cycloadditions have been applied towards the synthesis of 3-amino and 3-oxycyclopentadienones. These methods have provided an efficient means of generating [3.3.0], [4.3.0], and [5.3.0] bicyclic-cyclopentadienone ring systems. In an effort to probe the reactivity of our metal complexed dienones, we proceeded to subject them to cycloaddition reactions. With this goal in mind, we applied oxidative demetallation conditions to provide the metal free bicyclic-cyclopentadienones. Cycloaddition of the bicyclic-dienones with a number of pi donors and acceptors provided chemo and regioselective cycloadducts in an efficient fashion. Final studies included investigations of the iron cyclopentadienones in diastereoselective reactions.
