The tricyclic enedione, which was synthesized in the [2+2] photocycloaddition of homoquinone with alkyne, underwent a novel Lewis acid-mediated skeletal rearrangement to provide bi-, tri-and tetracyclic cage compounds, depending on the identity of the Lewis acid used.

The effect of Lewis acid catalysts on the mechanism of Diels-Alder reactions is studied using the MINDO/3 method. It is found that they tend to increase the two-step character of the process through a more important participation of the charge-transfer configuration.
