The title compound [systematic name: (1α,3α,6α,8β,13β,14α,16β)-20-ethyl-8-ethoxy-3,13-dihydroxy-1,6,16-trimethoxy-4-(methoxymethyl)aconitan-14-yl 4-methoxybenzoate], C₃₅H₅₁NO₁₀, was isolated from roots of Aconitum carmichaeli Debx., which is a typical C₁₉-diterpenoid alkaloid. The molecule has an aconitane carbon skeleton with four six-membered rings and two five-membered rings. The six-membered rings adopt chair conformations or boat conformations, while the five-membered rings have envelope conformations. Intramolecular O—H⋯O and O—H⋯N hydrogen bonds help to stabilize the molecular structure. Weak intermolecular C—H⋯O interactions occur in the crystal structure.

Comment top

The title compound, 8-O-ethylyunaconitine, was previously isolated from Aconitumcarmichaeli Debx., and its structure was established from the NMR and MS data. In our recent investigation, it was isolation from the root of Aconitum carmichaeli Debx, collected in the E'mei Mountain, Sichuan Province of China in August 2010, and its crystal structure was determined (Wang et al., 2009).

The molecular structure of the title compound is shown in Fig. 1. Six-membered rings A (C1/C2/C3/C4/C5/C11) and D (C8/C9/C14/C13/C16/C15) adopt boat conformations; six-membered ring B (C7/C8/C9/C10/C11/C17) adopts chair conformation; six-membered heterocyclic ring E (C4/C5/C11/C17/N1/C19) adopts 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, in which, the C14 and C11 act as the "envelope" respectively. The crystal structure contains intermolecular O—H···O and O—H···N hydrogen bonds. The intermolecular hydrogen bonds may be effective in the stabilization of the structure.

The absolute configuration of the title compound can not be confirmed by the present MoKa diffraction data. But it can be assumed to be the same as that reported for C₁₉-diterpenoid alkaloids from the nature (Wang et al., 2009).

Experimental top

Air-dried and powdered roots (600 g) were percolated with 0.1 M HCl (6 L). The obtained acid aqueous solution was basified with 10% aqueous NH₄OH to pH 11 and then extracted with ethyl acetate (6 L × 3). Removal of the solvent under reduced pressure afforded the total crude alkaloids (5.2 g) as a yellowish amorphous powder, which was chromatographed over a silica gel column, eluting with cyclohexane-acetone (7:1→1:2) gradient system, to afford 8-O-ethylyunaconitine (256 mg). The crystals suitable for X-ray structure analysis was obtained by slow evaporation from an acetone solution at room temperature.

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.
