(4aS,10aS)-7-Hydroxy-8-isopropyl-1,1,4a-trimethyl-1,2,3,4,4a,9,10,10a-octahydrophenanthrene: a new diterpenoid compound

A. Zeroual, N. Mazoir, J.-C. Daran, M. Akssira and A. Benharref

The new title diterpenoid compound, C₂₀H₃₀O, is a natural product isolated from Tetraclinis articulata wood via chloroform extraction. The asymmetric unit contains four molecules with the same S,S configuration, deduced from the chemical synthesis. Indeed, an overlay analysis, calculated using structure-matching software, shows that the four molecules can be superimposed. The central ring has a half-chair conformation, whereas the saturated ring displays a chair conformation.

Comment top

Among tricyclic diterpenoids, the class based on the phenanthrene skeleton is of great interest in alimentary, agricultural and cosmetic industries. Many of these substances exhibit biological activities that have been recently reported (Hedden & Philips, 2000; Duan et al., 2001; Rundle et al., 2001; Yang et al., 2002).

Within the context of our research for the chemical constituents of Tetraclinis articulata (Barrero et al., 2003), we have isolated two components structurally related to the diterpenoid skeletons (Zeroual, Mazoir, Berraho et al. (2007); Zeroual, Mazoir, Maya et al. (2007). The title compound (I), was isolated from Tetraclinis articulata wood using extraction with chloroform in a sohxlet apparatus.

The structure of (I) was established by ¹H and ¹³C NMR and confirmed by its single-Crystal X-ray structure. The unit cell in space group P1 contains four identical molecules having the same configuration (S,S). Indeed an overlay analyses calculated using the structure matching software (Watkin et al., 2003; Collins et al., 2006) shows that the four molecules could be superimposed (Table 1).

Each of these molecules is built up from three six-membered fused rings, a saturated one and two unsaturated (Fig. 1). The central rings display a half-chair conformation whereas the other unsaturated six-membered ring has a chair conformation (Cremer & Pople, 1975; Table 2).

Experimental top

50 g of Tetraclinis articulata wood was extracted with chloroform (300 ml) in a Sohxlet apparatus during 24 h. The CHCl₃ solution was cooled to yield, after solvent removal, one fraction (3.2 g) which was then subjected to silica gel column chromatography using hexane as an eluent afforded compound (I) in 64% yield. Suitable crystals of (I) were obtained by evaporation of a hexane solution at 277 K. m.p. = 373–374 K (hexane); Spectroscopic analysis: ¹H NMR (300 MHz, CDCl₃, δ, p.p.m.): 1.51 (2H2, m), 1.58 (2H3, m), 1.60 (2H4, m), 7.02 (1H5, d, J = 8.7 Hz), 6.60 (1H6, d, J = 8.7 Hz), 4.50 (OH, s), 2.84 (2H9, m), 1.58 (2H10, m), 1.76 (1H10a, dd, J₁ = 10.6 Hz, J₂ = 2.0 Hz), 3.11 (1H11, m), 1.30 (3H12, d, J = 10 Hz), 1.31 (3H13, d, J = 10 Hz), 0.97 (3H14, s), 0.98 (3H15, s), 1.11 (3H16, s); ¹³C NMR (75 MHz, CDCl₃, d, p.p.m.): 37.8 (C1), 41.6 (C2), 19.6 (C3), 39.6 (C4),37.5 (C4a), 131.1 (C4b), 123.0 (C5), 114.4 (C6), 152.1 (C7), 143.3 (C8), 134.1(C8a), 28.8 (C9), 19.5 (C10), 49.6 (C10a), 33.3 (C11), 20.1 (C12), 20.2 (C13), 22.4 (C14), 25.5 (C15), 24.6 (C16).

Special details top

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.
