Abstract
- The title compound, C <subscript>20</subscript> H <subscript>22</subscript> N <subscript>2</subscript> O <subscript>2</subscript> , an alkaloid isolated from the Madagascar periwinkle, crystallizes in P 1 with two independent but closely similar mol-ecules in the unit cell. The mol-ecules 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.
