The title steroid, C29H46O4, is a furostene derivative with a C=C double-bond length of 1.353 (3) Å and an E configuration. The side chain is oriented toward the α face of the AE steroidal nucleus and presents a disordered terminal CH2—OH group [occupancies for resolved sites are 0.591 (9) and 0.409 (9)]. The methyl group at C20 attached to ring E is also oriented toward the α face, avoiding steric hindrance with the carbonyl O atom of the acetyl group. The furostene and acetyl functionalities form an α,β-unsaturated ketone system, with an s-cis configuration. All hydr­oxy and carbonyl groups are involved in weak inter­molecular hydrogen bonds. The absolute configuration was assigned from the synthesis.

Comment top

We are interested in the preparation of new steroidal derivatives, through the cleavage of the F ring in sarsasapogenin (Sandoval-Ramírez et al., 2003; Meza-Reyes et al., 2004). Such reactions are valuable entries to furostenes; the title compound is a new representative of this family.

The molecular conformation of the title compound compares well with that previously observed for the corresponding diacetate (Sandoval-Ramírez et al., 2003). The functionality C22?C23 has a bond length of 1.353 (3) Å [1.355 (3) Å for the diacetate] and is E configured. The side chain C24/C25/C26/O26 is oriented toward the α face of the AE steroidal nucleus (Fig. 1). The terminal group CH2—OH is disordered over two positions (denoted a and b), and has a poorly defined geometry (see Experimental). The acetyl group substituting the furostenic atom C23 forms a s-cis α,β-unsaturated ketone system with the E configuration at the C22?C23 double bond. The methyl group C21 is placed on the α steroidal face, in agreement with a general rule followed by furostenes: the bulkier group at C20 avoids steric hindrance with groups substituting C23 (Meza-Reyes et al., 2004). The solid-state conformation of the title compound is retained in solution, as confirmed by NMR data.

The crystal structure contains rather weak intermolecular hydrogen bonds, involving all hydroxyl (O3', O26a/O26b) and carbonyl (O23") groups. The main contact, O3'—H3'···O23", links molecules into chains running in the [001] direction.

The diacetate of the title compound has been characterized by X-ray (Sandoval-Ramírez et al., 2003), as well as a related furost-22-ene derivate with the C20 site substituted by a methyl group and an acetyl group (Meza-Reyes et al., 2004).

Experimental top

(E)-(25S)-23-Acetyl-3β,26-diacetoxy-5β,16β-furost-22-ene (500 mg, 0.9 mmol) was added under stirring to a 10% ethanolic solution of KOH (25 ml), following the reaction course by TLC. After completion, the mixture was treated with saturated NaCl and washed with water. The organic phase was extracted using CH2Cl2 (3×30 ml) and then dried over Na2SO4. After removing solvent, the crude was chromatographed (ethyl acetate/hexane, 2:3). Single crystals were obtained from an ethyl acetate solution, at 298 K.

Refinement top

The final part of the lateral chain is badly disordered. Atoms C26 and O26 were modeled over two sites, and occupancies refined with the sum for a single atom constrained to 1. Site occupation factors converged to 0.591 (9) (C26a and O26a) and 0.409 (9) (C26b and O26b). Bond length C25—C26a was restrained to 1.50 (1) Å, while other dimensions were refined freely. The poor geometry for this part probably indicates that the actual disorder is more complex than a two-sites model. C-bonded H atoms were placed in idealized positions and refined as riding to their parent atoms. C—H bond lengths were fixed to 0.98 (methine CH), 0.97 (methylene CH2) or 0.96 Å (methyl CH3) and isotropic displacement parameters calculated as Uiso(H) = xUeq(carrier C) with x = 1.5 (CH3) or x = 1.2 (CH2 and CH). Disordered hydroxyl H atoms H26E and H26F were placed in idealized positions and refined fixing O—H bond lengths to 0.82 Å and Uiso(H) = 1.5Ueq(carrier O). Finally, hydroxyl H atom H3' was found in a difference map and refined with this as-found position and Uiso(H3') = 1.5Ueq(O3'). Measured Friedel pairs (1496) were merged for refinement.
