The title compound, C(20)H(22)N(2)O(2), an alkaloid isolated from the Madagascar periwinkle, crystallizes in P1 with two independent but closely similar mol-ecules in the unit cell. The mol-ecules are linked into pairs by two N-Hâ¯O=C hydrogen bonds. The absolute configuration was confirmed by anomalous dispersion effects as S at the 3 and 15 positions, and R at the 7 position.
