The title compound (systematic name: 8β-acetoxy-14α-benzoyloxy-N-ethyl-13β,15α-dihydroxy-1α,6α,16β-trimethoxy-4β-methoxymethyleneaconitane), C34H47NO10, is a typical aconitine-type C19-diterpenoid alkaloid, and was isolated from the roots of the Aconitum carmichaeli Debx. The molecule has an aconitine carbon skeleton with four six-membered rings and two five-membered rings, whose geometry is similar to these observed in other C19-diterpenoid both of five-membered rings have the envelope configurations and the six-membered N-containing heterocyclic ring displays a chair conformation. Intramolecular O—H⋯O hydrogen bonding occurs. Weak intermolecular C—H⋯O hydrogen bonding is observed in the crystal structure.

Air-dried and powdered roots (400 g) were percolated with 0.1 M HCl solution (5 L). The obtained acid aqueous solution was basified with 10% aqueous NH4OH to pH 10 and then extracted with ethyl acetate (6 L×3). Removal of the solvent under reduced pressure afforded the total crude →1:2) gradient system, to afford deoxyaconitine (180 mg) in cyclohexane-acetone (7:1) gradient system. The crystals suitable for X-ray structure analysis were obtained by slow evaporation from an acetone solution at room temperature.

Experimental. The absolute structure of the title compound can not be determined by the X-ray analysis, owing to the absence of strong anomalous scatterers. But it can be deduced by the comparision to the known diterpenoid alkaloids, for the unique absolute configuration of the similar natural products. |
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. |

The plant belonging to the genus A. carmichaeli Debx., which has been therapeutically used to treat rheumatic pain, paralysis due tostroke, rheumatoid arthritis and some other inflammations. The diterpenoid alkaloid, 3-deoxyaconitine, was previously isolated from A. carmichaeli Debx. (Pelletier et al. 1984), and its structure was established from the NMR and MS data. In our recent investigation, it was isolated from A. carmichaeli Debx., and its crystal structure was determined. The naming and the rings conforming referred to the literature (He et al., 2008). The molecular structure of the title compound is shown in Fig. 1. Six-membered rings A (C1/C2/C3/C4/C5/C11) and B (C7/C8/C9/C10/C11/C17) adopt chair conformations; six-membered heterocyclic ring E (C4/C5/C11/C17/N1/C19) adopt the same chair conformation; the five-membered rings C (C9/C10/C12/C13/C14) and F (C5/C6/C7/C17/C11) display an envelope conformation. while the six-membered ring D (C8/C9/C14/C13/C16/C15) adopt boat conformations. The crystal structure contains intermolecular O—H···O hydrogen bond between the hydroxy group and carbonyl O atom. The absolute configuration of the title compound can not confirmed by the MoKa diffraction data. But it could be determined throngh the comparion of the similar natural products for their unique and same configuration (Tashkhodjaev et al., 2009).
