Treatment of 2-(3, 4, 5-trimethoxyphenyl)-4, 5-dimethyl-A4-cyclohexenecarboxylic acid (C) with methanesulfonic acid yielded a mixture of the y-and &lactones II and E, and a mixture of bridged ring acids, consisting principally of trimethoxybenzodimethyl [2.2. 2] bicyclooctanecarboxylic acid (F). The structure of F was established by conversion of the amine F-5 (which is a mescaline analog of unusual type), degradation of the amine vsa ...
