Dienone–phenol type rearrangements. Part III. para-Quinols
Abstract
Three bicyclic p-quinols have been synthesised by lead tetra-acetate oxidation of the corresponding phenols and their rearrangements in acetic anhydride–sulphuric acid have been studied. Where rearrangement through a spiran intermediate is possible, this competes with 1,2-migration of the angular oxygen function. All potential rearrangement products have been synthesised by alternative routes.
