ACID CATALYZED RING CONTRACTIONS IN ENDO-2,8-TRIMETHYLENE-CIS-BICYCLOOCTYL CATIONS TO METHYLPERHYDROTRIQUINACENES. ONE OF THE METHYL EXTRUSION PROCESSES IN THE TRICYCLOUNDECANE REARRANGEMENT

Sulfuric acid catalyzed ring contractions with extrusion of a methyl group were examined for alcohol and olefin derivatives (28-31) of endo-2,8-trimethylene-cis-bicyclooctane (11), which was one of the two possible progenitors, among altogether 69
