The presence of the heptamethylene ring in these compounds is shown by the production of suberone by the exhaustive methylation, &c., of hydroecgoni dine ethyl ester (see POLYMETHYLENES and TROPINE).
Since both these substances have been synthesized (see Tropine), the artificial formation of atropine is accomplished.
