Glycozolidal

H.-K. Fun, W. Maneerat, S. Laphookhieo and S. Chantrapromma

Abstract: The title compound known as glycozolidal (systematic name: 2,7-dimethoxy-9H-carbazole-3-carbaldehyde), C15H13NO3, is a naturally occurring carbazole, which was isolated from the roots of Clausena lansium. The carbazole ring system is essentially planar, with an r.m.s. deviation of 0.0093 (1) Å. In the crystal, intermolecular N-H...O hydrogen bonds connect the molecules into a chain along the c axis. C-H...O, C-H...[pi] and [pi]-[pi] interactions, with centroid-centroid distances of 3.5924 (6), 3.6576 (6) and 3.8613 (6) Å, are also observed.
