The title compound, C18H26Cl2N2O, was synthesized in four steps from β-himachalene (3,5,5,9-tetramethyl-2,4a,5,6,7,8-hexahydro-1H-benzocycloheptene), which was isolated from an essential oil of the Atlas cedar (Cedrus atlantica). It crystallizes with two independent molecules in the Each molecule is built up from fused six- and seven-membered rings and an appended three-membered ring. An acetylhydrazone substituent is attached to the six-membered ring. In both molecules the six-membered rings display half-chair conformations, whereas the seven-membered rings have boat conformations. In the two molecules, the mean planes of the two rings are inclined to one another by 59.9 (3) and 59.1 (3)°. In the crystal, the two molecules are linked via N—H⋯O hydrogen bonds, forming dimers with an R22(8) loop. Within the dimer there are also C—H⋯O hydrogen bonds present. The dimers are linked via C—H⋯Cl hydrogen bonds, forming slabs parallel to the ab plane.

Structure description
The bicyclic sesquiterpene β-himachalene is the main constituent of the essential oil of the Atlas cedar (Cedrus atlantica) (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 having biological properties (El Jamili et al., 2002; Benharref et al., 2015). These compounds have been tested, using the food-poisoning technique, for their potential antifungal activity against phytopathogen Botrytis cinerea (Daoubi et al., 2004). In this paper we present the of the title compound, N′-[(1S,3R,8R)-2,2-dichloro-3,7,7,10-tetramethyltricyclo[6.4.0.01,3]dodecan-11-yl]acetohydrazide.
The title compound, Fig. 1, crystallizes with two independent molecules in the Each molecule is built up from fused six- and seven-membered rings and an appended three-membered ring. The six-membered rings each display a half-chair conformation, with puckering parameters of θ = 126.7 (7)° and φ2 = 169.4 (8) ° for the first molecule (C1/C8–C12), and θ = 53.4 (5)°, φ2 = 169.3 (7) ° for the second molecule (C1A/C8A–C12A). The seven-membered rings have boat conformations with θ = 88.2 (3) °, φ2 = −50.2 (3)° and φ3 = −93.40 (8)° for the first molecule (C1/C3–C8), and θ = 87.9 (3)°, φ2 =-50.6 (3)° and φ3 = −90.68 (8)° for the other molecule (C1A/C3A–C8A). In the first molecule, the mean planes of the two rings are inclined to one another by 59.9 (3)° [59.1 (3)° in the second molecule].
In the crystal, the two molecules are linked by two N—H⋯O hydrogen bonds, forming a dimer with an (8) ring motif (Fig. 2 and Table 1). Within the dimer there are also C—H⋯O hydrogen bonds present (Table 1). The dimers are linked via C—H⋯Cl hydrogen bonds, forming slabs lying parallel to the ab plane (Fig. 2 and Table 1).
Synthesis and crystallization
To a solution of an equimolecular quantity of (1S,3R,8R)-2,2-dichloro-3,7,7,10-tetramethyltricyclo[6.4.0.01,3]dodecan-11-one (Ourhriss et al., 2013) and thiosemicarbazide dissolved in ethanol, several drops of concentrated HCl were added. The reaction mixture was heated at reflux for 5 h and then evaporated under reduced pressure. The residue obtained was chromatographed on a silica gel column with a mixture of hexane and ethyl acetate as (80/20). 1 g (2.7 mmol) of thiosemicarbazone was dissolved in 2 ml of pyridine and 2 ml of acetic anhydride. The mixture was heated at reflux during 1 h with magnetic stirring, and then evaporated under reduced pressure. of the residue on silica (hexane/ethyl acetate, 90:10 v/v) allowed the isolation of the title compound with a yield of 90% (867 mg, 2.43 mmol). The product was recrystallized from ethyl acetate.

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. |
