The rearrangement of R,y-unsaturated ketones in acid has considerable potential for the synthesis of unusual bi-and tricyclic ring systems. In most examples described thus far, however, the double bond is present in the relatively strained cyclobutene ring.' We describe here a synthetically useful r
