The title compound, C15H14O4, also known as mansonone H, crystallizes in the space group P21212 with two mol­ecules in the asymmetric unit. In both mol­ecules, the tetra­hydro­pyran ring adopts an envelope conformation and the attached methyl group occupies an axial position. In the crystal structure, symmetry-related mol­ecules are linked by O—H...O and C—H...O hydrogen bonds, to form chains along the a and b axes. They are interlinked by C—H...O hydrogen bonds to form a network.

Comment top

Mansonone H, (I), was isolated from the roots of Helicteres angustifolia (Sterculiaceae) known as anti-inflammatory and antitumour medicine (Jiangsu New Medical Colleges, 1986). This cadinane sesquiterpenoid quinine has been previously isolated from the wood sawdust of Mansonia altissima Chev (Tanaka et al., 1966), the root bark of Ulmus davidiana (Kim et al., 1996) and the heartwood of Mansonia gagei Drumm (Tiew et al., 2002). The structure of (I) was previously elucidated on the basis of spectroscopic analysis. Herein, we report the crystal structure of (I).

The X-ray study of (I) confirms the previously proposed molecular structure based on spectroscopic data (Fig. 1). The asymmetric unit of (I) consists of two independent molecules, A and B, linked by a C13B—H13D···O3A hydrogen bond (Table 1). Bond lengths and angles observed in these two molecules agree with each other, but a large deviation is observed in the corresponding torsion angles about the C4—C12 bond. The C8A—C9A [1.523 (4) Å] and C8B—C9B [1.536 (4) Å] bond lengths are longer than the mean value of 1.478 (12) Å reported for unconjugated Csp2—Csp2 bonds by Allen et al. (1987). In both molecules, the tetrahydropyran ring adopts an envelope conformation and the methyl group occupies an axial position.

In the crystal, symmetry-related A molecules are linked by O1A—H1A···O3Ai and C2A—H2A···O3Aii hydrogen bonds, forming chains along the b axis. Similarly, symmetry-related B molecules are linked by O1B—H1B···O3Bi and C2B—H2B···O3Bii hydrogen bonds, forming chains along the a axis (symmetry codes are as in Table 1). The chains formed by molecules A and B are arranged alternately and C13B—H13D···O3A hydrogen bonds link them to form a network (Fig. 2).

Experimental top

Dried powder obtained from the roots of Helicteres angustifolia was extracted with EtOH. The EtOH extract was concentrated in vacuo, and the residue was extracted with EtOAc. The soluble portion of the EtOAc extract was subjected to silica-gel column chromatography, eluting with chloroform/menthol, yielded the title compound, mansonone H, (I). The compound was confirmed by the NMR spectra. Crystals of (I) were obtained from chloroform/menthol by solvent diffusion. 1H NMR (500 MHz, DMSO-d6): δ 6.78 (s, H5), 3.19 (m, H9), 4.43 (dd, J = 1.5, 5.0 Hz, H2a), 4.29 (dd, J = 1.5, 5.0 Hz, H2b), 1.83 (s, H9), 2.51 (s, H6), 1.20 (d, J = 7.0 Hz, H3).

Refinement top

The H atoms were positioned geometrically and were treated as riding on their parent C and O atoms, with C—H distances in the range 0.93–0.98 Å and O—H distance of 0.82 Å. The reflections (001) and (110) were omitted during the refinement as they fit very badly. One of the anisotropic displacement parameters (U33) for the carbonyl atom O4A is large, indicating a possible disorder. Owing to a large fraction of weak data at higher angles, the completeness of tha data is slightly low. The Friedel opposites were merged during the refinement.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s 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 > σ(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. All H atoms were placed in calculated positions and refined as riding atoms.
