15α,20β-Dihydr­oxy-6β-meth­oxy-6,7-seco-6,20-ep­oxy-1,7-olide-ent-kaur-16-ene

Abstract

The title compound, C21H30O6, a natural ent-kaurane diterpenoid, was obtained from the medicinal plant Isodon serra. The five rings in the mol­ecule exhibit the expected cis and trans junctions. The three six-membered rings adopt chair, twist-boat and boat conformations, while two five-membered rings adopt envelope conformations. There are two mol­ecules in the asymmetric unit, related by a non-crystallographic twofold screw axis; the main difference is in the different degrees of distortion of ring B. In the crystal, the mol­ecules are linked by inter­molecular O—H(...)O hydrogen bonds, forming chains along the b axis.

Comment

The title compound, 15α,20β-dihydroxy-6β-methoxy-6,7-seco-6,20- epoxy-1,7-olide-ent-kaur-16-ene, C21H30O6 (I) is a natural ent-kaurane diterpenoid isolated from the medicinal plant Isodon serra which is widely distributed in China. The plant material is used for the treatment of acute jaundice, hepatitis and acute cholecystitis in folk medicine. We extracted the leaves of Isodon serra, collected in the Henan province of China and obtained the title compound, and its structure was postulated from spectroscopic methods (Yan et al., 2007). The X-ray crystallographic analysis confirms this proposed molecular structure (Fig. 1) and represents a second crystallographically characterized ent-kaur-16-ene compound isolated from Isodon plant material. The asymmetric unit of (I) contains two independent but similar molecules. In these there is a trans junction between ring A (C1—C5/C10) and ring B (C7—C10/C1/O2); cis junctions are present between ring B and ring C (C8/C9/C11—C14), ring C and ring E (C8/C13—C16), and ring A and ring D (C5/C6/O1/C20/C10). Ring A adopts a chair conformation, with an average torsion angle of 50.02 (2) °. Ring C adopts a boat conformation, while ring B adopts a twist boat conformation because of the presence of a carbonyl group. Ring D and ring E show envelope conformations. The two hydroxyl groups at C15 and C20 adopt α and β-orientations respectively, while the methoxy group at C6 adopts a β-orientation. Bond lengths and angles are within expected ranges (Allen et al., 1987), with average values (Å) in the first molecule: Csp3—Csp3 = 1.543 (3), Csp3—Csp2 = 1.524 (3), Csp2—Csp2 (CC) = 1.326 (2), Csp3—O = 1.424 (2), and Csp3—Csp3 = 1.545 (3), Csp3—Csp2 = 1.525 (3), Csp2—Csp2 (CC) = 1.324 (2), Csp3—O = 1.448 (2) in the second molecule.

Compound (I) contains eight chiral centers at C1(S), C5(R), C8(S), C9(S), C10(R), C13(R), C15(R), and C20(S). Although the absolute configuration could not be reliably determined from anomalous dispersion effects, the negative optical rotation shows this compound to be of the ent-kaurane series as reported for the genus Isodon (Sun et al., 2001), rather than of the kaurane series, allowing us to assign the correct configuration. In the crystal structure, intermolecular O—H···O hydrogen bonds (Table 1) are effective in the stabilization of the structure and are responsible for the formation of one-dimensional chains extending down the b axis of the unit cell (Fig. 2).

Experimental

The dried and crushed leaves of Isodon serra (11 kg), collected from Henan Province, China, were extracted four times with Me2CO/H2O (7:3, v/v) at room temperature over a period of six days. The combined extract was filtered and the solvent was removed under reduced pressure. The extract was suspended in water and then partitioned successively with AcOEt, then concentrated to obtain a residue, which was then subjected to column chromatography over silica gel. Recrystallization from CHCl3/CH3OH (10:1), gave 55 mg of the title compound (m.p. 469-470 K; optical rotation: [α]D23 -141.0° (c 0.19, CH3OH). Crystals suitable for X-ray analysis were obtained by slow evaporation of a solution in CH3OH at room temperature.

Refinement

All H atoms were included in calculated positions and refined as riding atoms, with C—H = 0.98Å (CH3), 0.99Å (CH2), and 1.00Å (CH), and with Uiso(H) = 1.2 Ueq(C). In the absence of significant anomalous scattering effects, Friedel pairs were merged. The choice of the enantiomer was based on comparison of the optical rotation with that of related compounds having known stereochemistry.

Special details

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. 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.
