Allylcyclohexadienones

The most commonly encountered examples of this type arc the 4-allylcyclohexadienones and their derivatives, such as (88), which undergo room temperature Cope rearrangement, followed by aromatiza-tion, in the presence of acid7 - It is interesting that the 3,3-Cope rearrangement competes with 1,2-migration (acid-catalyzed dienone-phenol rearrangement).
