The title compound was isolated from the roots of Aconitum carmichaeli Debx. according to the literature procedure of Gao et al. (2010) and crystals of X-ray quality were grown from acetone at room temperature by slow evaporation.
Hydroxy H atoms were located in a difference Fourier map and refined as riding in their as-found relative positions with Uiso(H) = 1.5Ueq(O). Other H atoms were located geometrically with C—H = 0.93–0.98 Å, and refined using a riding model with Uiso(H) = 1.5Ueq(C) for methyl and 1.2Ueq(C) for the others. The
has not been determined from the X-ray analysis, owing to the absence of strong and Friedel's pairs were merged. Bond distance restraints for three bonds were applied. The was assigned on the basis of the related literature (Pelletier & Djarmati, 1976; Tsuda & Marion, 1963; Zhapova et al., 1986).As a famous Chinese traditional herbal, the plant Aconitum carmichaeli Debx. known as fuzi, has been therapeutically used to the treatment of rheumatic pain, rheumatoid arthritis and some other inflammations. The title compound 8β-acetoxy- 14α-benzoyloxy-N-methyl-13β,15α-dihydroxy-1α,6α,16β-trimethoxy-4β-(methoxymethylene)aconitane, hypaconitine, has been isolated previously from A. carmichaeli Debx. (Pelletier et al. 1984), and its structure was established from the NMR and MS data. However, the of hypaconitine has not been reported. In view of this, the determination of the title compound was carried out and the results are presented here.
The molecular structure of the title compound is shown in Fig. 1. Six-membered ring 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) adopts the same chair conformation; the five-membered rings C (C9/C10/C12/C13/C14) and F (C5/C6/C7/C17/C11) display an
While the six-membered ring D (C8/C9/C14/C13/C16/C15) adopt boat conformations. The contains intermolecular O—H···O hydrogen bond between the hydroxy group and carbonyl O atom. The of the title compound can not be 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 (He et al., 2008).The title compound, a famous Chinese traditional herbal medicine, is an aconitine-type C19-diterpenoid alkaloid, which is isolated from the roots of Aconitum carmichaeli Debx., known as fuzi.

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. |

As a famous Chinese traditional herbal, the plant Aconitum carmichaeli Debx. known as fuzi, has been therapeutically used to the treatment of rheumatic pain, rheumatoid arthritis and some other inflammations. The title compound 8β-acetoxy- 14α-benzoyloxy-N-methyl-13β,15α-dihydroxy-1α,6α,16β-trimethoxy-4β-(methoxymethylene)aconitane, hypaconitine, has been isolated previously from A. carmichaeli Debx. (Pelletier et al. 1984), and its structure was established from the NMR and MS data. However, the crystal structure of hypaconitine has not been reported. In view of this, the crystal structure determination of the title compound was carried out and the results are presented here.
The molecular structure of the title compound is shown in Fig. 1. Six-membered ring 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) 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. 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 be 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 (He et al., 2008).
