The title compound, C24H40O3·C2H6O, is a substituted tetracyclo[10.2.2.01,10.04,9]hexadecane derivative obtained from the reduction of maleopimaric acid which was isolated from a maleic anhydride modified rosin. In the crystal, the triol molecule and the ethanol solvent molecule are linked by hydroxyl O—H⋯O hydrogen bonds, giving a two-dimensional network structure.

Maleopimaric acid (12.0 g) was dissolved in tetrahydrofuran (300 ml) at 263 K while stirring vigorously and lithium aluminium hydride (6.9 g) was added over a period of 2 h. The reaction was maintained for 1 h at reflux temperature after which water (6.9 ml) and 10% sodium hydroxide solution (6.9 ml) were added dropwise at 263 K. The mixture was filtered and the filtrate was concentrated, giving the crude product which was recrystallized with ethanol, giving the title compound. Crystals suitable for X-ray diffraction were obtained by slow evaporation of an ethanol solution.
All H atoms bonded to the C atoms were placed geometrically with C—H distances of 0.93–0.98 Å and included in the
in a riding motion approximation, with Uiso(H) = 1.2 or 1.5Ueq of the All hydroxyl H atoms were placed geometrically at distances of 0.82–0.85 Å. The absolute configurations for the 8 chiral centres in this molecule could not be determined and the configurations for the chosen were C1(R), C5(R), C6(R), C7(R), C8(S), C12(R), C13(R), C14(R).Data collection: CAD-4 Software (Enraf–Nonius, 1989); cell

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. |

As an important natural resource, large amounts of rosin are available in China. Nowadays, rosin and its Diels-Alder adducts have been developed as a feedstock for synthesizing various chemicals and intermediates. Maleopimaric acid was isolated from maleic anhydride modified rosin (Halbrook & Lawrence, 1958), and its crystal structure has been reported (Rao et al., 2008). The title compound C24H40O3 . C2H6O (I) was obtained on reduction of this tricarboxylic acid. The asymmetric unit comprises a triol molecule and an ethanol molecule of solvation (Fig. 1). In the crystal structure the molecules are linked by hydroxyl O–H···O hydrogen bonds and other interactions (Table 1, Fig. 2), giving a two-dimensional network structure. The absolute configurations for the 8 chiral centres in this molecule could not be assigned from the analysis: the configurations for the chosen enantiomer were C1(R), C5(R), C6(R), C7(R), C8(S), C12(R), C13(R), C14(R).
