The title compound, C₂₂H₂₉F₃O₅S [systematic name: (3S,8R,9S,10R,13S,14S)-10,13-dimethyl-17-(trifluoromethylsulfonyloxy)-2,3,4,7,8,9,10,11,12,13,14,15-dodecahydro-1H-cyclopenta[a]phenanthren-3-yl acetate], contains a fused four-ring steroidal system. Rings A and C adopt a chair conformation, while rings B and D adopt half-chair and envelope (with the fused CH atom as the flap) conformations, respectively. In the crystal, weak intermolecular C—H⋯O interactions link the molecules into layers parallel to the ab plane.

Keywords: crystal structure; chiral space group; 3β-acetoxyandrosta-5,16-dien-17-yl trifluoromethanesulfonate; C—H⋯O interactions.

Structural commentary top

The title compound, 3β-acetoxyandrosta-5,16-dien-17-yl trifluoromethanesulfonate (I) (Fig. 1), is an intermediate of the synthesis of abiraterone acetate which is a pro-drug for 17-(pyridin-3- yl)androsta-5,16-dien-3P-ol, or abiraterone, a potent inhibitor of human cytochrome P450₁₇_α (steroidal 17α-hydroxylase-C_17,20-lyase) (Attard et al. 2009). 3β-Acetoxyandrosta-5,16-dien-17-yl trifluoromethane- sulfonate was first synthesized and charaterized by Potter et al. (1995), but structural data were not obtained. In this work, we obtained a single-crystal of (I) and present here its crystal structure.

The title molecule contains a fused four-ring steroidal system. The two saturated six-membered rings A and C adopt chair conformations,while ring B with one double bond adopts a half-chair conformation, and ring D with one double bond adopts an envelope conformation. The absolute structure of (I), which is crystallized in a chiral space group P2₁2₁2₁, was reliably determined based on the value of Flack parameter [0.02 (3)]. In the crystal, weak intermolecular C—H···O interactions link the molecules into layers parallel to ab plane.

Synthesis and crystallization top

3β-Acetoxyandrosta-5,16-dien-17-yl trifluoromethanesulfonate was synthesized from dehydro-epiandrosterone acetate via trifluoromethanesulfonic anhydride with an overall yield of 58% according to a literature method (Potter, 1995). Colourless crystals were obtained by evaporation from a hexane solution.

Refinement top

Crystal data, data collection and structure refinement details are summarized in Table 1. Crystal data, data collection and structure refinement details are summarized in Table 1. All H-atoms bound to carbon were refined using a riding model with d(C—H) = 0.93 Å, for aromatic, 0.98 Å for C—H and 0.97 Å for CH₂ with U_iso = 1.2U_eq (C). d(C—H) = 0.96 Å with U_iso = 1.5U_eq (C) for CH₃ H atoms. The absolute structure could be determined reliably.

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.
