Crystal structure of 3,4a,7,7,10a-penta-methyl-3-vinyl-dodeca-hydro-1H-benzo[f]chromen-9-ol isolated from Sideritis perfoliata.

The asymmetric unit of the title compound, C20H34O2, contains two crystallographically independent mol-ecules (1 and 2) with similar conformations. In both mol-ecules, the cyclo-hexane rings adopt a chair conformation, while the oxane rings are also puckered. In the crystal, O-H⋯O hydrogen bonds connect adjacent mol-ecules, forming C(6) helical chains located around a 21 screw axis and running along the crystallographic a axis. The packing of these chains is governed only by van der Waals inter-actions. Semi-empirical PM3 quantum chemical calculations are in a satisfactory agreement with the structural results of the X-ray structure analysis. The absolute structure was indeterminate in the present experiment.

Chemical context

The Sideritis genus belonging to the Lamiaceae family is represented by more than 150 species in the world (Duman 2000 ▸). Sideritis species have been reported to have a broad spectrum of biological activities such as anti-inflammatory, anti-oxidant, anti-ulcerogenic, analgesic, anti­microbial, anti­proliferative, anti-HIV and anti­feedant activities (González-Burgos et al. 2011 ▸), and they have been consumed as teas, as flavoring agents, for therapeutic purposes, etc. In particular, Sideritis teas have been used for gastrointestinal disorders such as stomach ache and indigestion, to alleviate common colds, fever, flu and sore throats (Topçu et al. 2002 ▸). Phytochemical investigations of the species have revealed the presence of terpenes (Fraga et al. 2003 ▸), flavonoids, essential oils and other secondary metabolites (Barberan et al. 1985 ▸). As part of our studies in this area, we now describe the isolation and structure of the title compound, (I).

Structural commentary

In the title compound (Fig. 1 ▸), the asymmetric unit contains two crystallographically independent mol­ecules, 1 and 2, with a similar conformations. In mol­ecule 1, the cyclo­hexane ring (C1–C6) attached to the OH group and the central cyclo­hexane ring (C1/C6/C9–C12) each adopt a chair conformation with puckering parameters Q T = 0.536 (3) Å, θ = 0.0 (3), φ = 270 (81)° and Q T = 0.584 (3) Å, θ = 4.4 (3), φ = 59 (4)°, respectively. The oxane ring (O2/C11/C12/C15–C17) is also puckered, with puckering parameters Q T = 0.551 (3) Å, θ = 12.1 (3) and φ = 133.5 (16)°. The equivalent rings in mol­ecule 2 (C21–C16, C21/C26/C29–C32 and O4/C31/C32/C35–C37) have as puckering parameters Q T = 0.534 (3) Å, θ = 1.9 (3), φ = 296 (11)°, Q T = 0.583 (3) Å, θ = 5.0 (3), φ = 72 (3)° and Q T = 0.554 (3) Å, θ = 11.9 (3), φ = 127.2 (15)°, respectively. Bond lengths and angles are within normal range, comparable with each other and with those reported for similar structures in the literature (e.g., Evans et al., 2011 ▸).

Supra­molecular features

Inter­molecular O—H. . . O hydrogen bonds connect adjacent mol­ecules, forming C(6) helical chains located around a 21 screw axis running along the crystallographic a axis (Table 1 ▸ and Fig. 2 ▸). The crystal packing of these chains is governed only by van der Waals inter­actions. The two asymmetric molecules lead to pseudo-41 symmetry in space group P212121.

Theoretical calculations

PM3 (parameterized model number 3) is a semi-empirical method for the quantum calculation of the mol­ecular electronic structure in computational chemistry. It is based on the neglect of differential diatomic overlap integral approximation. The semi-empirical PM3 parameterization used in the MOPAC program is widely used to derive charges, dipole moments and bond lengths. The computed quantum chemical descriptors include bond lengths, bond angles, torsion angles, atom charges, HOMO and LUMO energy levels, dipole moment, polarizability, etc. In the present case, the geometry of the mol­ecule of the title compound was calculated with a semi-empirical PM3 method (Stewart, 1985 ▸). A spatial view is included in the Supporting information.

The calculated net charges at atoms O1 and O2 are −0.257 and −0.309 e−, respectively. The total energy and dipole moment of the title mol­ecule are −3514.7 eV and 1.695 Debye. The HOMO and LUMO energy levels are −10.36 and 2.71 eV, respectively.

Calculated values for the geometrical parameter are consistent with those obtained by the X-ray structure determination, within the error limits (see Table S1 in the Supporting information), with the sole exception of the angles in the meth­oxy groups. This may be ascribed to the steric inter­actions between adjacent mol­ecules in the crystal structure.

Synthesis and crystallization

The aerial part of the plant material (5 g) was extracted with ethyl acetate (3 × 20 mL). After removal of the solvent by rotary evaporator, the extract was subjected to column chromatography (2.5 × 70 cm); sephadex LH-20 (50 g) was used as a stationary phase and methanol was used as a mobile phase with a 0.25 ml min−1 flow rate. 16 fractions, each of which was 150 mL, were collected. Similar fractions were combined according to the TLC profile. Further purification was carried out with silica gel column chromatography to isolate the title compound. Colourless prisms were recrystallized from ethanol solution.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. H atoms bound to oxygen were found from difference Fourier maps and their positional parameters were refined with U iso fixed at 1.5 times U eq(O). H atoms bound to carbon were positioned geometrically and allowed to ride on their parent atoms with U iso = 1.2U eq(C) (C—H = 0.93 Å for aromatic, 0.97 Å for methyl­ene and 0.98 Å for methine) and with U iso = 1.5U eq(C) (C—H = 0.96 Å) for methyl H atoms. The absolute structure was indeterminate in the present experiment.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell esds are taken into account in the estimation of distances, angles and torsion angles

Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > 2sigma(F2) is used only for calculating -R-factor-obs 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.
