The title compound, C17H27NO, crystallizes with three independent mol­ecules in the asymmetric unit with almost identical conformations. Each mol­ecule is built up from a seven-membered ring to which a bridged six-membered ring is fused. In each of the three mol­ecules, the seven-membered rings have a twist-chair conformation, while the cyclo­hexenyl rings display perfect boat conformations. In the crystal, N—H⋯O hydrogen bonds link the mol­ecules into zigzag chains running along the b-axis direction.

Structure description

The bicyclic sesquiterpene α-himachalene is a constituent (20%) of the essential oil of the Atlas cedar (Cedrus Atlantica) (El Haib et al., 2010[El Haib, A., Benharref, A., Parrès-Maynadié, S., Manoury, E., Daran, J. C., Urrutigoïty, M. & Gouygou, M. (2010). Tetrahedron Asymmetry, 21, 1272-1277.]; Loubidi et al., 2014[Loubidi, M., Agustin, D., Benharref, A. & Poli, R. (2014). C. R. Chim. 17, 549-556.]). The reactivity of this sesquiterpene and its derivatives has been studied extensively by our team (El Jamili et al., 2002[El Jamili, H., Auhmani, A., Dakir, M., Lassaba, E., Benharref, A., Pierrot, M., Chiaroni, A. & Riche, C. (2002). Tetrahedron Lett. 43, 6645-6648.]; El Haib et al., 2011[El Haib, A., Benharref, A., Parrès-Maynadié, S., Manoury, E., Urrutigoïty, M. & Gouygou, M. (2011). Tetrahedron Asymmetry, 22, 101-108.]; Loubidi et al., 2014[Loubidi, M., Agustin, D., Benharref, A. & Poli, R. (2014). C. R. Chim. 17, 549-556.]; Benharref et al., 2016[Benharref, A., Oukhrib, A., Ait Elhad, M., El Ammari, L., Saadi, M. & Berraho, M. (2016). IUCrData, 1, x160703.], 2017[Benharref, A., El Ammari, L., Saadi, M., Mazoir, N., Daran, J.-C. & Berraho, M. (2017). IUCrData, 2, x170584.]) in order to prepare new products with biological properties. Indeed, these compounds have been tested, using the food-poisoning technique, for their potential anti­fungal activity against the phytopathogen Botrytis cinerea (Daoubi et al., 2004[Daoubi, M., Durán-Patrón, R., Hmamouchi, M., Hernández-Galán, R., Benharref, A. & Collado, I. G. (2004). Pest Manag. Sci. 60, 927-932.]). Herein, we report the synthesis and crystal structure of the title compound, synthesized by the reaction of 6α,7α- ep­oxy­himachalene with BF3OEt in aceto­nitrile under argon.

The asymmetric unit of this new compound contains three independent mol­ecules with similar conformations. Each mol­ecule is built up from a seven-membered ring, which is fused to a bridged cyclo­hexenyl ring as shown in Fig. 1[link]. In each of the three mol­ecules, the seven-membered ring displays a twist-chair conformation as indicated by the total puckering amplitude QT = 0.864 (3) Å, a spherical polar angle θ = 39.60 (2)°; φ2 = 342.4 (3)° and φ3 = 301.6 (3)°, whereas the cyclo­hexenyl ring shows a perfect boat conformation with QT = 0.865 (3) Å, a spherical polar angle θ = 88.7 (2)° and φ2 = 125.08 (18)°.

In the crystal, the three mol­ecules are linked by N—H⋯O hydrogen bonds, forming zigzag chains running along the b-axis direction (Fig. 2[link] and Table 1[link]). Adjacent chains form sheets of mol­ecules in the bc plane (Fig. 3[link]).

Synthesis and crystallization

2 g (9 mmol) of 8,9-ep­oxy-2methyl­ene-6,6,9-triméthylbi­cyclo [5.4.01,7]undecane (Lassaba et al., 1998[Lassaba, E., El Jamili, H., Chekroun, A., Benharref, A., Chiaroni, A., Riche, C. & Lavergne, J.-P. (1998). Synth. Commun. 28, 2641-2651.]) was dissolved in 30 ml of CH3CN and stirred at 273 K under argon. BF3OEt (3% mmol) was added and the reaction mixture was stirred and monitored by TLC. After the completion of reaction, the solvent was removed and the residue obtained was chromatographed on silica, eluting with hexa­ne–ethyl­acetate (90:10), which allowed the isolation of the title compound (yield: 1.5 g, 5.7 mmol, 64%).

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.

Refinement. 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), 1.0Å (methine) with Uiso(H) = 1.2Ueq(CH and CH2) or Uiso(H) = 1.5Ueq(CH3). The coordinates of H atoms attached to N atoms were freely refined with Uiso(H) = 1.2Ueq(N) and the H attached to hydroxyl O atoms were fixed geometrically and treated as riding with O—H = 0.84Å and Uiso(H) = 1.5Ueq(O).
