The potassium-liq. ammonia cleavage of O-methylpilocereine was carried out in order to re-examine the structure (Ia) of pilocereine. In addition to the expected bases (II, IIIb, IVa, and IIIa), isopilocereine (Ia) and a phenolic base which is considered to be V were obtained. This result and new molecular formula C_<45>H_<65>O_6N_3 proposed lately by Djerassi, et al. pointed out the structure of pilccereine to be VIa. The formation of isopilocereine on treatment of pilocereine with potassium-liq. ammonia was illustrated as a normal cleavage reaction.
