In the title mol­ecule, C27H32O2, the aromatic rings are in a propeller configuration. In the crystal, mol­ecules are linked through O—H⋯O hydrogen bonds forming a two-dimensional network which develops parallel to (010). Futhermore, weak C—H⋯π inter­actions involving the two substituted rings build up a three-dimensional network.

R-(-)-Carvone, p-mentha-6,8-dien-2-on, is the major constituent of spearmint essential oil of Menthe spicata (Gershenzon et al., 1989). This monoterpene ketone is used as a fragrance component and flavouring agent. R-(-)-Carvone is also an important chiron for the synthesis of complex natural products (Wang et al., 2001) and antiviral agents. Recently, we reported an efficient method which affords direct access to p-cymene derivatives from R-(-)-carvone (Majidi & Fihi, 2004). In our continuing interest (Majidi et al., 2005) in the development of strategies for the synthesis of natural products derivatives, we report herein the synthesis of carvacrol derivatives from R-(-)-carvone.

The condensation of arylaldehydes (2a-c) to (R)-(-)-carvone (1) in acid media at reflux in toluene leads to carvacrol derivatives (3a-c), respectively. Products (3a-c) were obtained by a condensation followed by a rearrangement (Fig. 1). Since the 1H and 13C NMR studies did not provide unambiguous information on the structure of (3), a single-crystal X-ray study was carried out for the product (3a).

In the molecule of the title compound the phenyl rings are in a propeller configuration with roughly identical dihedral angles between the rings: 88.27 (8)° between the C11-C16 and C21-C26 rings, 85.79 (6) between the C21-C26 and C31-C36 rings and 82.52 (8)° between C31-C36 and C11-C16 rings (Fig. 2). Propeller like arrangement has been observed in several related compounds, e.g., CH(C6H5)3 (Veldman et al., 1996), CH(C6H5)2[C6H2(OH)2CH(C6H5)2](C6H5CHO) (Guo et al., 2005), CH(C6H5)(C6H4OH)2,0.17(H2O) (Sarma & Baruah, 2005), CH(C6H5)[C6H2(CH3)2OH]2 (Sarma & Baruah, 2004), CH(C6H5)[C6H2(OH)2Cl]2,C2H6O,H2O and CH(C6H5)[C6H2(OCH3)2Cl]2(Yang et al., 2005). The bond distances and angles in the title molecule agree with the corresponding distances and angles reported in the structures quoted above.

In the crystal, the molecules are linked through O—H···O hydrogen bonds involving the donor oxygen atom O24 and the acceptor O34 forming infinite chains. These chains are further connected through weak O—H···O hydrogen bonds involving as donor atom O34 and as acceptor O24 (Table 1) resulting in the formation of a two dimensionnal network developping parallel to the (0 1 0) plane (Fig. 3; Table 1).

Futhermore, weak C—H···π interactions involving the C13 and C15 atoms and the centroids Cg2 and Cg3 of the C21-C26 and C31-C36 rings, respectively, build up a three dimensionnal network (Table 1).

Experimental top

(R)-(-) Carvone (1) is a commercial product. A mixture of carvone (3 g, 2 mmol), corresponding aromatic aldehyde (1.06 g, 10 mmol) in toluene (50 ml) and TsOH.H2O (p-toluene sulphonic acid hydrate) (0.28 g) was heated under reflux using a Dean-stark trap for 24 h. The reaction mixture was poured into cold water (100 ml), and extracted. The organic phase was washed with water (4 x 30 ml), dried (Na2SO4), and evaporated in vacuo. The crude products were purified by column chromatography on silica gel. Eluant: hexane/dichloromethane (60/40). The compound was finally recrystallized from ethanol.

Refinement top

All H atoms attached to C atoms and O atom were fixed geometrically and treated as riding with C—H = 1.0Å (methine), 0.98 Å (methyl) or 0.95 Å (aromatic) and O—H = 0.84 Å with Uiso(H) = 1.2Ueq(C) or Uiso(H)= 1.5Ueq(O, C-methyl).

In the absence of significant anomalous scattering, the absolute structure could not be reliably determined and then the Friedel pairs were merged and any references to the Flack parameter were removed.

Special details top

Experimental. Empirical absorption correction using spherical harmonics, implemented in SCALE3 ABSPACK scaling algorithm, CrysAlis RED (Oxford Diffraction, 2006).

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.
