STEROIDS: PART IV. CONDENSATION OF CHOLESTAN-3-ONE AND CHOLESTANE-3,6-DIONE WITH FORMALDEHYDECholestan-3-one and cholestane-3,6-dione were allowed to react under the conditions of the Mannich reaction with paraformaldehyde and amine hydrochlorides. The products obtained proved to be methylene-bis-...
