(Received 13 May 2013; accepted 16 May 2013; online 22 May 2013)

The title compound, C15H20O5, presents a bis­norsesquiterpene skeleton, with a trans-deca­line backbone constrained by the lactone bridge. The α-hy­droxy substituent and the methyl group belonging to the two deca­line rings are in axial positions, whereas the other methyl group and the acyl group occupy the sterically preferred equatorial positions. The mol­ecular structure is stabilized by an intra­molecular C—H⋯O hydrogen bond. In the crystal, mol­ecules are linked into chains along [010] by O—H⋯O hydrogen bonds

Comment top

Several nardosinane sesquiterpene derivatives, extracted from different soft corals (Lemnalia, Paralemnalia, Rhytisma and others), have already expressed promising biological properties (Bishara et al. 2008; Huang et al. 2011; Lu et al. 2011; Petit et al. 2004; Wang et al. 2012) while the potential of others remains to be explored (El-Gamal et al. 2005; Huang et al. 2006; Wang and Duh 2007; Wang et al. 2010). In our continuing interest in the total synthesis of biologically active compounds, we have recently proposed a synthetic strategy to access such sesquiterpene derivatives. In the course of the synthesis, the title compound appeared as an analogue structurally close to the natural lactone Paralemnolide A (Wang et al. 2012) which possesses cytotoxic activity. We report herein on the crystal structure of a new nardosinane sesquiterpene analogue.

The title compound presents a bisnorsesquiterpene skeleton, with a trans-decaline backbone constrained by the lactone bridge. The α-hydroxy substituent and the methyl group belonging to the two decaline rings are in an axial position, whereas the other methyl group and the acyl group occupy the sterically preferred equatorial position. In the crystal, the molecules form chains connected by O-H···O hydrogen bonds. The crystal structure is further stabilized by C-H···O contacts.

Experimental top

Title compound was synthesized according to the reported method (Selaimia-Ferdjani et al., 2013): To a solution of diene 1 (100 mg, 0.38 mmol) in CH2Cl2 (2.5 ml) at 0°C was added via cannula a solution of mCPBA (350 mg, 0.38 mmol) in CH2Cl2 (5.0 ml). After 20 min, the reaction mixture was quenched with saturated NaHCO3 solution (10 ml). The aqueous layer was extracted with CH2Cl2 (3 x 25 ml) then the combined organic layers were washed with brine (50 ml), dried over MgSO4, filtered and concentrated under vacuum. The residue was purified by flash chromatography (eluant Petroleum Ether-EtOAc 100/0 to 7/3) to afford lactone 2 (title compound) (63 mg, 60%) as a solide. Crystals suitable for X-ray structure analysis (colorless crystals) were obtained by slow evaporation of a solution of the title compound in ethyl acetate/hexane (1:1, v/v) at room temperature. mp = 434 K; [α]20D= - 17 (c = 0.29 in CH2Cl2); 1H NMR (400 MHz, CDCl3) d 6.28 (ddd, J6–5 = 10.1 Hz, J6–7 = 4.7 Hz, J6–7 = 1.5 Hz, 1H, H6), 5.69 (d, J6–5 = 10.1 Hz, 1H, H5), 5.45 (ddd, J2–1 = 3.1 Hz, J3–2 = 7.2 Hz, J3–2 = 10.4 Hz, 1H, H2), 4.27 (d, J4–3 = 6.6 Hz, 1H, H4), 2.82 (d, J2–1 = 3.1 Hz, 1H, H1), 2.39 (m, 1H, H3), 2.15 (s, 3H, H13), 1.91–2.35 (m, 4H, H3, H7, H7, H8), 1.27 (s, 3H, H10), 0.90 (d, J8–11 = 6.5 Hz, 3H, H11).

Refinement top

H atoms bonded to C atoms were positioned with idealized geometry and were refined with Uiso(H) = 1.2× Ueq(C)) using a riding model with C—H = 0.96 Å. The H atom bonded to the O atom was located from a difference Fourier syntheses and it was freely refined.
