(Received 18 June 2013; accepted 3 July 2013; online 24 July 2013)

The absolute configuration of the title compound, C16H26O, was determined as (1R,3S,8R,11R) based mainly on the synthetic pathway but is also implied by the X-ray analysis. The mol­ecule contains fused six- and seven-membered rings. Part of the seven-membered ring was refined as disordered over two sets of sites with the occupancy ratio fixed at 0.86:0.14. The disorder corresponds to a major chair conformation and a minor boat conforation. In the crysyal, O—H⋯O hydrogen bonds connect the mol­ecules into chains parallel to the a axis.

Comment top

Optically active allylic alcohols are highly interesting building blocks that have been widely used in organic transformations (Paresh & Sujit, 2012; Arfaoui et al., 2010). Allylic alcohol functionality is also found in several potent biologically active compounds (Chung et al., 2007; Servi et al., 2000). In the aim of preparing chiral allylic alcohols with sesquiterpenic squeleton, we report herein, the crystal structure of the title compound (1R,3S,8R,11R)-3,7,7,10-tetramethyltricyclo[6.4.0.01, 3]dodec-9-en-11-ol (II). The title compound prepared by treating (1S,3S,8R)-3,7,7,10-tetramethyltricyclo[6.4.0.01,3]dodec- 9-ene(I) (Auhmani et al., 2001), with N-bromosuccinimide (NBS).

The molecular structure of (II) is shown in Fig. 1. As observed in related compounds (Gassman & Goman, 1990; Lassaba et al., 1997; Benharref et al., 2010) the molecule contains a fused six-membered and seven-membered ring. The six-membered ring has approximate half-chair conformation with the puckering parameters: Q = 0.452 (2) Å, spherical polar angle θ= 128.8 (3)° and ϕ= 153.4 (4)° (Cremer & Pople, 1975), whereas the seven-membered ring displays either a chair conformation (86%) with a total puckering amplitude of 0.797 (3) Å (Boessenkool & Boyens, 1980) or a boat conformation (14%) with a total puckering amplitude of 1.230 (4) Å. The major chair confornation and minor boat conformation corresponds to the disorder in part of the seven-membered ring.

Although the standrad uncertainties on the Flack's parameter (Flack, 1983; Flack & Bernardinelli, 2000), -0.1 (3), and on the Hooft parameter (Hooft et al., 2008), 0.04 (15) are rather high and limit the reliability of the observed value, the absolute configuration (1R,3S,8R,11R) agrees with the one expected from the synthetic pathway. It addition, inverting the configuration leads to values close to 1 for both Flack and Hooft parameters.

In the crystal, the hydroxyl group is engaged in O—H···O hydrogen bonding with symmetry related molecules forming infinite chains parallel to the a axis (Fig. 2).

Experimental top

To a cooled (273 K) solution of (I) (4.6 mmol) in 50 ml of a solvent mixture THF/H2O (4/1, v/v), NBS (9,16 mmol) was added in small portions, then mixture was kept under stirring at 273 K, for two hours. After completion of the reaction, a 15% sodium hydrogenocarbonate solution was added and the reaction mixture was taken up in ether, dried over anhydrous sodium sulfate, and concentrated. The crude product was purified by chromatography on silica gel (230–400 mesh) with Hexane/ethyl acetate (96:4) as eluent to give the title compound in 20% yield. X-ray quality crystals were obtained by slow evaporation from a petroleum ether solution of the title compound.

Refinement top

All H atoms attached to C atoms were fixed geometrically and treated as riding with C—H = 0.99 Å (methylene), 0.98 Å (methyl), 0.95 Å (methine) with Uiso(H) = 1.2Ueq(CH and CH2) or Uiso(H) = 1.5Ueq(CH3). The hydrogen atom of the hydroxyl group was refined with a restraint of O—H = 0.88 (1)Å.

The C6 carbon atom is disordered over two positions inducing a disorder of the two methyl groups C14 and C15 attached to C7. This disorder was modelled using the tools available in SHELXL97 (Sheldrick, 2008). The two disordered fragment were included in two different parts, PART 1 and 2. The occupancy factor for the two sites was refined using the free variable restraining the sum of the occupancy factors to be equal to 1. The occupancies were ultimately fixed. To be able to calculate the disordered hydrogen atom positions, atom C5 was split in two identical positions which were restrained to have same coordinates and anisotropic thermal parameters by using the EXYZ and EADP instructions in SHELXL97 (Sheldrick, 2008).

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 > 2σ(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.
