3β-Chloro­cholest-5-en-7-one

Abstract

The title compound, C27H43ClO, is a steroid derivative composed of a saturated carbon fused-ring framework with an alkyl side chain. The A and C rings have chair conformations and the B and D rings assume half-chair conformations. The cholesterol side chain is fully extended with a gauche, trans conformation of the terminal methyl groups. In the crystal structure, the molecules are aligned in an antiparallel fashion, forming alternate layers. These layers are then linked via C—H(...)O hydrogen bonds, forming a three-dimensional network.

Comment

Although the basic biological functions of cholesterol have been known for many years, little is known about its molecular interactions with enzymes, cholesterol-binding proteins and related effectors of gene transcription. A series of crystal structures of the esters and carbonates of cholesterol (Ahn & Park, 1990; Kang et al., 1985; Yun et al., 1989; Park & Shin, 2002; Park, 2004) has been examined in order to obtain structural information relevant to the liquid crystalline phases and the possible modes of association of the cholesterol derivatives themselves, as well as of other substances in biological systems (Abrahamsson et al., 1977). In view of the biological importance of cholesterols, we report here the crystal structure of the title compound (I) - a new cholesterol derivative.

In the asymmetric unit of the title compound (Fig. 1), the A (C7–C12) [Q = 0.5302 (18)Å, Θ = 168.67 (19)° and [var phi] = 324.7 (10)°] and C (C13–C16/C3/C4) [0.5636 (17)Å, Θ = 172.25 (16)° and [var phi] = 119.9 (13)°] rings have chair conformations (Cremer & Pople, 1975), and the B (C4–C7/C12–C13) [Q = 0.4830 (16)Å , Θ = 51 (19)° and [var phi] =313.6 (2)°] and D (C1–C3/C16/C17) [Q = 0.4653 (17)Å and [var phi] = 273.6 (2)°] rings assume half-chair conformations. The torsion angles C20-C21-C22-C23 of 61.84 (18)° and C20-C21-C22-C24 of -175.12 (13)° show that the terminal isopropyl group has a (-)-gauche conformation. This type of conformation was also observed in the crystal structure of cholesteryl isobutylcarbonate (Park et al., 2005). There are eight chiral centres in the molecule. The absolute configurations of these sites were determined by the refinement of the Flack parameter. From the structure presented, these sites exhibit the following chiralities: C3 = S, C4 = S, C9 = S, C12 = R, C13 = S, C16 = R, C17 = R and C18 = R.

In the crystal structure, the molecules are aligned in an antiparallel fashion to form alternate layers. These layers are then linked via C—H···O (Table 1) hydrogen bonds to form a three dimensional network

Experimental

A solution of butyl chromate [t-butyl alcohol (60 mL), CrO3 (20 g), acetic acid (35 mL) and acetic anhydride (10 mL)] was added at 0°C to a solution of 3β-chlorocholest -5-ene (8 g) in CCl4 (150 mL), acetic acid (30 mL) and acetic anhydride (10 mL). The content was refluxed for 3 h and then diluted with water. The organic layer was washed with sodium bicarbonate solution (5%) and water and then dried over anhydrous sodium sulphate. Evaporation of the solvents under reduced pressure furnished 3β-chlorocholest-5-en-7-one which was crystallized from methanol (3.4 g), m. p. 144°C (reported, m. p.144 -145°C ).

Refinement

All hydrogen atoms were positioned geometrically [C–H = 0.93–0.98Å] and were refined using a riding model, with Uiso(H) = 1.2-1.5 Ueq(C). 2745 Friedel pairs were used to determine the absolute configuration.

Special details

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K.
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 > 2sigma(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.
