The title compound, C19H17N3O2, was obtained from fruits of Evodia Rutaecarpa. In the solid state, the dihedral angle between the 2,3,4,9-tetra­hydro-1H-pyrido[3,4-b]indol-1-one (tetra­hydro-β-carbolinone) unit and the benzoyl ring is 61.46 (3)°. In the crystal, dimers are formed through inter­molecular N—H⋯O hydrogen-bonding inter­actions. In addition, intra­molecular N—H⋯O hydrogen bonds are also observed. C—H⋯π contacts connect the dimers, leading to the formation of a three-dimensional supra­molecular network.

The title compound, C19H17N3O2, is a tetrahydro-beta-carbolinone derivative isolated from the fruits of Evodia rutaecarpa. The tetrahydro-beta-carbolinone ring is a structural unit found in natural products. It possesses significant biological activities and plays an important role as an intermediate for the synthesis of more complex alkaloids and further functionalized polycyclic systems of biological interest (Yamada et al., 1986; Jokela et al., 1987; Vicente et al., 2008). Herein, the conformation of the title compound has been determined by single-crystal analysis and further confirmed by mp, IR, and NMR.

As depicted in Fig. 1, the structure of the title compound, is made up of a 2-(methylamino)benzoyl ring and a tetrahydro-beta-carbolinone ring. Bond distances (Allen et al., 1987) and angles are as expected and agree with the corresponding bond distances and angles reported in a related compound (Wakchaure et al., 2009). The tetrahydro-beta-carbolinone ring adopts a twist conformation with atom C10 displaced by 0.547 (2) Å from the plane defined by the atoms C1-C9/C11/N1/N2. The dihedral angle between the benzoyl (C12-C18) and the tetrahydro-beta-carbolinone ring (C1-C9/C11/N1/N2) is 61.46 (3)°. An intramolecular N—H···O hydrogen bonding interactions is observed in the title compound. Two pairs of intermolecular N—H···O hydrogen bonding interactions [graph set motif is R22(10)] lead to the formation of a dimer (Bernstein et al., 1995) (Table 1). Finally, the dimers are linked into a three-dimensional supramolecular network through C—H···π stacking interactions (Fig. 2). The H-to-centroid distances of H11A···Cg1i = 3.668 (2), H10A···Cg2ii = 2.865 (3), H5···Cg2iii = 3.082 (4) and H19B···Cg1iv = 2.876 (2) Å [Cg1 and Cg2 are the centroids of the C1, C2, C3, C4, C5, C6 ring, and C13, C14, C15, C16, C17, C18 ring, respectively.

Experimental top

Dried and powdered fruits (10 kg) of Evodia rutaecarpa (juss.) were extracted with 80% EtOH (10000 mL) under reflux with a soxhlet extractor. After removing the solvent, the extract (2136 g) was suspended with water and partitioned with petroleum ether (333K-363K boiling range), CHCl3, EtOAc and n-BuOH, successively. The CHCl3 extract was evaporated to give 158 g of residues, which were separated on a silica gel (200-300 mesh) column by elution with CHCl3-MeOH (20:1 to 2:1) increasing polarity to give 30 fractions (2000 mL per fraction). The title compound (500 mg) was isolated from the fractions 20-22 (yield 0.32%). Single crystals suitable for X-ray diffraction were prepared by slow evaporation of a solution of the title compound in CHCl3 at room temperature.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
