0.2 mmol compound were dissolved in 10 ml methanol and 10 ml CH2Cl2. The resulting red solution was filtered. The filtrate was allowed to sit under ambient conditions for two weeks, dark-red block crystals were obtained.
The H bound to C atoms of naphthoquinone, and to C(11) as well as to C(12)—C(14) were treated as riding, with C—H distances of 0.93, 0.96 and 0.97Å with Uiso(H) = 1.2Ueq(C), respectively. Hydroxyl O—H distances were set to 0.82Å and were refined as riding with Uiso(H) = 1.5Ueq(O).
Plumbagin is a potent toxic natural product extracted from Plumbago Zeylanica L. (Plumbaginaceae), which has been used in China as well as other Asian countries for the treatment of rheumatoid arthritis, dysmenorrhea, injury by bumping, and even cancer. The title compound is a 2-substituted 1,4-naphthoquinone derivative. Its synthesis has been reported by Salmon-Chemin et al.(2001), we now report its structure. The molecular structure of the title compound is shown in Fig.1. The bond lengths and angles of the napthoquinone molecule are normal and comparable to those of plumbagin (Ghouse & Rao, 1974; Vijayalakshmi, et al., 1987). Geometric parameters for the butanoic acid group are also normal. As shown in Fig.2, a two-dimensional network is generated via intermolecular hydrogen bond interactions involving C—H···O, O—H···O.

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. |

Plumbagin is a potent toxic natural product extracted from Plumbago Zeylanica L. (Plumbaginaceae), which has been used in China as well as other Asian countries for the treatment of rheumatoid arthritis, dysmenorrhea, injury by bumping, and even cancer. The title compound is a 2-substituted 1,4-naphthoquinone derivative. Its synthesis has been reported by Salmon-Chemin et al.(2001), we now report its structure. The molecular structure of the title compound is shown in Fig.1. The bond lengths and angles of the napthoquinone molecule are normal and comparable to those of plumbagin (Ghouse & Rao, 1974; Vijayalakshmi, et al., 1987). Geometric parameters for the butanoic acid group are also normal. As shown in Fig.2, a two-dimensional network is generated via intermolecular hydrogen bond interactions involving C—H···O, O—H···O.
