media and, in acid solution, varied with time. Rearrangement of the spirocyclic precursor to the non-fused, bicyclic skeleton (present in olefins 11 and 12) is favored kinetically; but, on prolonged treatment in acid, the fused bicyclic skeleton (present in alkenes 19 and 20) increases in amount at the expense of 11 and 12. We also examined acid-catalyzed isomerizations of olefin 19 as well as of 11
