title: (7R,8S,9S,12S)-1-Benz-yloxy-13,14-didehydro-12-hy-droxy-2,13-dimeth-oxy-N-methyl-morphinane.
abstract: In the title compound, C(26)H(31)NO(4), a sinomenine derivative, the angle between the two aromatic rings is 53.34 (4)°. The N-containing ring is in a chair conformation, while the other two non-planar rings are in a half-boat conformation. In the crystal, mol-ecules are linked by O-H⋯N inter-actions into a C(8) chain along [100].
