Structure description
The Atlas cedar (Cedrus atlantica), native to Morocco, is the source of essential oils made up mainly (75%) of bicyclic sesquiterpene hydrocarbons, among which is found the compound β-himachalene (El Haib et al., 2011). The reactivity of this sesquiterpene and its derivatives has been studied extensively by our team in order to prepare new products with potential biological properties (El Jamili et al., 2002; Zaki et al., 2014; Benharref et al., 2015). For example, these compounds have been tested for their potential anti-fungal activity against the phytopathogen Botrytis cinerea (Daoubi et al., 2004).
The structure of the title compound was determined as part of our ongoing studies in this area. The molecule is built up from two fused six- and seven-membered rings which is linked to a three-membered ring. An additional toluensulfonic acid group system is attached to the six-membered ring (Fig. 1). The six- and seven- membered rings display boat conformations, as indicated by the total puckering amplitude QT = 0.730 (2) Å and spherical polar angle θ = 88.03 (14)° with φ = −170.60 (14)° for the six-membered ring and QT = 1.134 (2) Å, θ = 88.22 (10), φ2 = −51.43 (10) and φ3 = −62.95 (3)° for the seven-membered ring. Owing to the presence of Cl and S atoms, the was confirmed as C1(1S, C3(R), C8(R), C9(S)and C10(R). No directional interactions beyond typical van der Waals contacts could be identified in the crystal.
Synthesis and crystallization
Diborane was prepared by addition at 0°C of 2.5 g (17 mmol) of boron trifluoride etherate in 0.5 g (12.6 mmol) of sodium borohydride in 30 ml of diglyme. The diborane formed was driven by a stream of dry nitrogen in 2 g (7 mmol) of (1S,3R,8R)-2,2-dichloro-3,7,7,10-tetramethyltricyclo[6.4.0.01,3]dodec-9-ene (El Jamili et al., 2002) dissolved in 20 ml of tetrahydrofuran at 273 K. This took about 4 h, then 2 ml of sodium hydroxide 3 N was added carefully between 263 K and 273 K in 15 minutes, and then 2 ml of 30% hydrogen peroxide in the vicinity of 298 K. The reaction mixture was then extracted with diethyl ether. The organic phase was washed to neutrality and the solvent was evaporated under vacuum. The residue obtained was chromatographed on a column of silica gel with pentane–ethyl acetate (95/5), which allowed the isolation of pure (1S,3R,8R,9S,10R)-2,2-dichloro-3,7,7,10-tetramethyltosyltricyclo[6.4.0.01,3]dodecan-9-ol. 1 g (3.3 mmol) of the latter compound was dissolved in pyridine (10 ml). The solution was cooled to 10°C and tosyl chloride (0.6 g, 3.3 mmol) in pyridine (4 ml) was added dropwise. The reaction mixture was stirred overnight and treated with 10 ml of water and extracted with dichlormethane. The organic phase was evaporated and the residue obtained was chromatographed on a column of silica gel with hexane and ethyl acetate (97/3) as to give the sesquiterpene tosylate, with a yield of 87% (1.3 g, 2.8 mmol). The title compound was recrystallized from its ethyl acetate solution.

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. |
