The title compound, C₂₉H₃₇NO₂, crystallized with two independent molecules in an asymmetric unit in which the conformation of the cyclohexyl ring of the pregnene moiety bonded to the 3α-(1,3-dioxoisoindolin-2-yl)- ring system differs: in one molecule it is in a chair conformation, while in the other it exhibits a half-chair conformation. The other six-membered rings in the pregnene moiety are in chair conformations and the five-membered rings are in envelope forms in both molecules. In both molecules, the 3α-(1,3-dioxoisoindolin-2-yl)- ring systems are individually approximately planar, with r.m.s. devtaions 0.0148 and 0.0264 Å. The structure is consolidated by intermolecular C—H⋯O hydrogen-bonding interactions involving the carbonyl O atoms and methyl, methylene and methylidyne groups, resulting in a two-dimensional structure.

Comment top

The title compound was synthesized from epiandrosterone which is a pregnane alkaloids isolated from Pachysandra axillaris, a Traditional Chinese Medicine (TCM). The pregnane alkaloids from Pachysandra axillaris had been reported to be effective as anticancer (Sun et al., 2010).

The title compound, crystallizes with two independent molecules in an asymmetric unit. The cyclohexyl rings (A) of the pregnene moiety bonded to the 3α-(1,3-dioxoisoindolin-2-yl)- ring system in both molecules differ in conformations; in one molecule (Fig. 1) it is in a chair conformation while in the other molecule (Fig. 2) it exhibits a half chair conformation. The conformations of the rings B–D in the two molecules are identical with six membered rings (B & C) in chair conformations and the five membered rings in envelope forms in both molecules. In both molecules, the 3α-(1,3-dioxoisoindolin-2-yl)- ring systems are individually planar with rms devtaions 0.0148 and 0.0264 Å. The structure is consolidated by intermolecular hydrogen bonding interactions of the type C—H···O involving carbonyl O atoms and methyl, methylene and methylidyne groups, resulting in a two-dimensional structure (Fig. 3).

Experimental top

The title compound was prepared by following a literature procedure (Batcho et al., 1981). A solution of potassium t-butoxide (t-BuOK) (2.28 g, 20.0 mmol) in 15 ml THF was added to a suspension of Ph₃PEtBr (7.58 g, 20.0 mmol), in 25 ml dry THF, and was stirred for 1 h at room temperature. The mixture was refluxed for another 4 h after adding epiandrosterone (1.45 g, 5.0 mmol). The residue thus obtained was purified by recrystallization from MeOH to afford 1 (675.8 mg, 45%; Fig. 4). To a solution of 1 (86.9 mg, 0.287 mmol) and triphenylphosphine (85.1 mg, 0.324 mmol) in THF (12 ml), phthalimide (46.5 mg, 0.316 mmol) and diisopropyl azodicarboxylate (63.9 mg, 0.316 mmol) were added, and the mixture was stirred for 18 h at room temperature. The residue was purified by crystallization from MeOH to afford the title compound, 2 (78.0 mg, 63%) as a white solid. The crystals of 2 were obtained by slow evaporation of its solution using a mixed solvent MeOH/CH₂Cl₂ (1:1).

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.
