1-(2-ピペリジニル)-2-プロパノン

説明An alkaloid of this name was discovered by Tanret but when this alkaloid was shown to be (±)-pelletierine, the name was adopted for this particular base isolated from Punica granatum. The alkaloid is an oily liquid which yields a number of well crystalline salts and derivative: the hydrochloride, m.p. 143°C; hydrobromide, m.p. 149°C; picrate, m.p. 147 -8°C and the picrolonate, m.p. 185-6°C. The N-acetyl derivative is an oily liquid, b.p. 110-5°C/0.I mm while the N-benzoyl compound is crystalline with m.p. 72-4°C. The alkaloid may be prepared by the demethylation of methylisopelletierine, the action being revers_x0002_ible.
