Blanc (Comptes rendus, 1903, 136, p. 1460), prepared hydrocarbons of the cyclo-pentane series from cyclo- hexane compounds by the exhaustive methylation process of A.
It is identical' with the hydrotropilidine, which results by the destructive methylation of tropane.
On oxidation it yields methyl granatic ester, which, by the exhaustive methylation process, is converted into homopiperylene dicarboxylic ester, HO 2 C CH :CH CH 2 CH 2 CH :C. H CO 2 H, from which suberic acid may be obtained on reduction.
By the electrolytic reduction of pseudopelletierine, N-methyl granatanine is obtained, and this by exhaustive methylation is converted into A O des-dimethyl granatanine.
It combines directly with methyl iodide to form dimethyl coninium iodide, C10H22NI, which by the destructive methylation process of A.
