bromide and with toluene-p-sulphonic acid, by mild hydrogenation, and by irradiation with ultraviolet light. Structures are proposed for all the compounds obtained, mainly by comparing their proton magnetic resonance spectra with those of similar compounds of known structure. The acids opened the epoxide ring, the anions entering the endo-position without molecular rearrangement. Hydrogenation first removed
