A sample of Virola venosa bark was collected in the Amacayacu National Park in the Colombian Amazon region. The botanical determination was realised by Roberto J. Mejia from the Institute of Science, Universidad Nacional de Colombia. A voucher specimen of the plant has been deposited in the National Herbarium of Colombia, No COL-366258. For the isolation of the compound, the dried and ground bark (1.8 kg) was extracted with ethanol (96%) at ambient temperature. After removal of the solvent, the crude extract (27 g) was treated with petroleum ether (b.p. 233–353 K), yielding, after evaporation of the solvent, a liquid (4.30 g) and a solid phase (6.10 g). The solid phase (5.0 g) was washed with methanol (3 × 2 ml) to afford the dry crude product (380 mg). Flash column chromatography was performed using a mixture of toluene/ethyl acetate (98:2) and silica gel Merck G. The combined fractions containing the compound were evaporated to dryness to yield the pure arylalkanone (184 mg). Crystallization was realised in methanol, yielding colourless geometrically homogeneous needles with a melting point of 325–326 K. The spectroscopic data are more accurate than but in agreement with literature data (Kato et al., 1985).
The absolute configuration could not be determined because of the absence of a strong anomalous scatterer in the crystal. Therefore, for the final refinement, 199 Friedel pairs were merged.

Ethnobiological studies carried out in Colombia have shown that native tribes use species of Virola (Myristicaceae plant family) for the treatment of a large variety of sicknesses, such as treatment of mental instability, infected wounds, skin infections, colic and vitiligo (Schultes & Holmstedt, 1971). Virola venosa (Benth.) Warb. (Myristicaceae) is a tropical tree endemic in altitudes between 200 and 1300 m above sea level. The plant reaches an average height of 30 m, with a trunk diameter of 35 cm, and has been reported both in the Brazilian Amazon region, where it is known as `ucuuba-da-mata', and in the Colombian departments Amazonas and Vaupes (Herrera, 1994). Previous publications reveal that blooms, fruits and seeds contain flavanoids, lignanes, arylalkanones and sitosterol. In leaves and roots, alkaloids and stilbenes have been detected (Kato et al., 1992). Studies on bioactivity of species from the Virola plant family showing antimalaria (Lopes et al., 1999), anti-inflammatory (Carvalho et al., 1999), antifungal (Lopes et al., 1999a; Sartorelli et al., 1998) and antileishmanial activities (Barata et al., 2000) have been reported. The sample of the bark of Virola venosa used in the present study was collected in the Amacayacu National Park in Leticia, capital of the Colombian department Amazonas. The isolation and purification of (I) was carried out by means of chromatographic techniques. The compound was crystallized in methanol and its structure was elucidated using NMR techniques, mass spectrometry and IR spectroscopy.
The 1H-NMR spectrum of (I) shows a rare signal at 18.28 p.p.m., which was interpreted as an intramolecular hydrogen bond. X-ray structure analysis shows that the unit cell contains two independent molecules, both with intramolecular hydrogen bonds. The H atoms involved in hydrogen bonding have been located. In fact, peaks for all 64 H atoms of the two molecules of (I) unambiguously emerged from difference Fourier maps. Both independent molecules (labelled A and B) show sp2-hybridization-related electron delocalization over atoms O6, C6, C1, C7 and O7, and atoms C1, C2 and O2; this delocalization is manifested in both molecules by an average C—C bond length of 1.435 Å (Table 1). In addition, the C2A=O2A and C2B=O2B bond lengths [1.218 (3) and 1.217 (3) Å, respectively] exhibit the properties of regular double bonds, while the C=O bond lengths of the two sp2 centers at C6 and C7 are significantly elongated in both molecules (see Fig. 1 and Table 1) and have bond orders that are intermediate between double and single bonds. The strong intramolecular hydrogen bonds between atoms O6A and O7A, and atoms O6B and O7B (Table 2), in which the H atom appears not to be strictly covalently bonded to either O atom, are nearly identical within statistical significance, but in molecule B, the H atom appears to be more localized at atom O6 (see Fig. 1 and Table 2). We attribute the signal at 18.28 p.p.m. in the 1H NMR spectrum of (I) to the H atom involved in these strong intramolecular hydrogen bonds. In solution, these differences in intramolecular hydrogen bonding disappear, as only a single resonance is observed in this region of the NMR spectrum. This fact is consistent with the possibility that any differences between molecules A and B may be related to the packing in the crystal structure, as discussed below. The cyclohexane-2,6-dione system of (I) shows an envelope-like conformation, similar to that reported for (5R,S,6R,S)-2-acetyl-3,5,6-trihydroxy-5,6- dimethyl-2-cyclohexenone, (II) (Adembri et al., 1988). Like (I), (II) forms a very strong intramolecular hydrogen bond, and these hydrogen bonds are favoured by the presence of conjugated systems in both cases. The least- squares planes through these conjugated systems [HO7(6)···O6—C6—C1—C7—O7] for both molecules of (I) show a maximum deviation of 0.034 (2) Å. Each molecule also contains an additional intramolecular hydrogen bond, between hydroxy atom the O3 and neighboring O2 carbonyl groups (Table 2), but in this case, the hydrogen bonding is more traditional, with atom HO3 in both molecules uniquely bonded to the hydroxy O atom. This bond leads to a lack of protonation at atoms O2A and O2B, the HO3A···O2A and HO3B···O2B distances [1.83 (3) and 1.95 (4) Å] being significantly longer than all other hydrogen bonds present in the two molecules (see Table 2). As a consequence, atoms HO3A and H03B belong to normal alcohol functions bonded to sp3 centers, their signals occurring at 4.04 p.p.m. in the 1H NMR spectrum. The C—O bond lengths at these sp3 centers [1.416 (3) and 1.403 (4) Å] are typical of single bonds.
The packing in the present structure of (I) features an alternating head-to- tail arrangement (Fig. 2). This is induced by an approximate center of symmetry at the origin. The symmetry breaks down at the chiral atom C3, while the pseudo-center of symmetry extends otherwise throughout the entire packing scheme. A survey of the literature has yielded at least one additional structure where a pseudo-center of symmetry occurs in space group P1 (Olovsson et al., 2001). Consistent with the existence of the approximate center of symmetry in the crystal structure, we have observed that the average absolute value of E*E-1 for (I) is 1.027, clearly consistent with the presence of the pseudo-center.
As anticipated by the presence of approximate symmetry, we have observed that overall the conformations of the two molecules are nearly identical. An exception is the ring O2—C2—C3—O3 torsion angle, which is −16.9 (3)° in molecule A and −12.7 (3)° in molecule B. This small, but significant difference may be related to a close intermolecular contact between molecules A, in which atom O6A is 2.57 Å from H3A, the H atom bonded to C3A in a symmetry-related molecule [symmetry code: x − 1, y, z; Fig. 2]. The fact that this close approach occurs uniquely for only one molecule, but not for the other, clearly shows that the pseudo-center of symmetry at (0, 0, 0) is disrupted by the presence of only one enantiomer of (I). Thus, the analogous H atom, H3B attached to C3B, of the second molecule [symmetry code: x − 1, y, z] points away from atom O6B (see Figs. 1 and 2) and no close approach is possible. It seems likely that this packing difference has an influence on the intramolecular hydrogen bonds between atoms O6 and O7 in both molecules. The close contact removes electron density from atom O6A, and therefore atom HO7A is located closer to atom O7A in molecule A than atom HO6B is to atom O6B in molecule B (see Fig. 1 and 2).
In summary, (I) belongs to the group of arylalkanones or acylaryl-recorcinoles that have been found in several species of Virola (Myristicaceae plant family), for example V. elongata (Kato et al., 1985), V. surinamensis (Blumenthal et al., 1997), V. sebifera (Kato et al., 1985) and V. venosa (Kato et al., 1992), in the last of which this compound has been detected in the fruits. By contrast, this article reports, for the first time, the presence of (I) in the bark of the plant; the hydrogen bonding in (I) has been established.
