【 摘 要 】

The title compound, C20H22N2O2, an alkaloid isolated from the Madagascar periwinkle, crystallizes in P1 with two independent but closely similar mol­ecules in the unit cell. The mol­ecules are linked into pairs by two N—H⋯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.
