In the title cholesterol analogue, [systematic name: (3S,8S,9S,10R,13S,14S,17R)-17-{(S)-1-[4-(2-hydroxypropan-2-yl)-1H-1,2,3-triazol-1-yl]-6-methylheptan-2-yl}-10,13-dimethyl-2,3,4,7,8,9,10,11,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthren-3-ol] C32H53N3O2, a new chain, including an intermediate triazole and a tertiary hydroxyl group in the terminal position, has been added at position 20 inducing a change in its stereochemistry. In the crystal, molecules are linked by O—H⋯O and O—H⋯N hydrogen bonds, forming layers lying parallel to (-201) and enclosing R44(36) ring motifs. The isopropyl group is disordered about two positions with a refined occupancy ratio of 0.763 (5):0.237 (5). A region of disordered electron density was corrected for using the SQUEEZE routine in PLATON (Spek (2015). Acta Cryst. C71, 9–18). The given chemical formula and other crystal data do not take into account the unknown solvent molecule(s).

1. Chemical context
The nuclear receptors (NRs) are a large family of ligand-regulated transcriptional factors and include the receptors for steroid hormones, thyroid hormones, lipophilic vitamins and cholesterol metabolites (Mangelsdorf & Evans, 1995; Burris et al., 2013
). Approximately half of NRs are classified as orphan NRs because they do not have well-characterized ligands (Hummasti & Tontonoz, 2008
). Orphan NRs are an active area of research partly due to their potential for clinical agent development for various diseases (Mohan & Heyman, 2003
). Recent studies have demonstrated that retinoic acid receptor-related orphan receptors (RORs) have been implicated in several physiological and pathological processes.
Using the methodology developed in our research group for the synthesis of gemini-type vitamin D analogues (Fall et al., 2011; Pazos et al., 2016
; Santalla et al., 2017
) (modified with a double side chain), we can access new cholesterol analogues that can be of great interest in interactions with RORs. In this study, we present the structure of a new analogue of cholesterol (2), with eight stereocentres and a double side chain based on the aliphatic chain of cholesterol on the one hand and on the incorporation of a triazole ring on the other, since many azasteroids have proven to be biologically active. For example, some of them act as 5α-reductase inhibitors, antifungal agents and γ-aminobutyric acid (GABA) receptor modulators (Tian et al., 1995
; Burbiel & Bracher, 2003
; Covey et al., 2000
).
2. Structural commentary
In the title cholesterol gemini-type analogue 2, illustrated in Fig. 1, the four aliphatic rings are structurally identical to those in the cholesterol hormone, i-cholesteryl methyl ether (Bernal et al., 1940
; Wang et al., 2014
). In the title compound, atom C20 has a different stereochemistry than in the cholesterol molecule, as a result of stereospecific reactions of the synthetic pathway. Furthermore, a new chain, including an intermediate triazole and a tertiary hydroxyl group in the terminal position, has been added at atom C21. Although some steroid analogues with a triazole ring have been synthesized (Seck et al., 2015
), there are no references to any crystallographic analyses of gemini cholesterols with a triazole group at position C21 (Cambridge Structural Database, version 5.39, last update February 2018; Groom et al., 2016
). The terminal OH group (C2′/C3′/O3′) is inclined to the triazole ring (N1′–N3′/C1′/C2′) mean plane by 7.2 (2) °.

3. Supramolecular features
The molecular association in the title compound 2, is based on hydrogen bonding involving the hydroxyl and triazole groups (Table 1). These intermolecular links are present in the form of two chains. The first, a C(18) chain (Fig. 2
), is formed by the O3—H3⋯O3'i hydrogen bond with O3—H3 acting as the donor and atom O3′ acting as the acceptor. The second is a C(5) chain, in which the triazole group participates, and is formed by hydrogen bond O3′—H3′⋯N3'ii (Fig. 3
); the alcohol group O3′—H3′ acts as the donor towards the acceptor atom N3′. The combination of these interactions results in the formation of layers lying parallel to the (
01) plane, as shown in Fig. 4
, and encloses R44(36) ring motifs, details of which are illustrated in Fig. 5
.

4. Synthesis and crystallization
Compound 2: details of the synthesis are illustrated in Fig. 6. To a solution of triazole 1 (12 mg, 0.022 mmol;) in tBuOH (2 ml) and water (1 ml) was added p-TsOH (5 mg) and the mixture was heated to 353 K for 3 h. The reaction mixture was diluted with water and then extracted with CH2Cl2 (3 × 5 ml). The combined organic layers were dried with Na2SO4, filtered, and concentrated. The residue was purified by flash (50% EtOAc/hexane) to afford the title diol (11 mg, 99%). Compound 2 was recrystallized as colourless prisms by slow evaporation of a solvent mixture of dichloromethane/diethyl ether (1:1) at room temperature [yield 99%; m.p. 778 K; Rf: 0.10 (30% EtOAc/hexane)].

5. Refinement
Crystal data, data collection and structure . The O—H and C-bound hydrogen atoms were positioned geometrically (O–H = 0.84 Å, C—H = 0.95–1.00 Å) and refined using a riding model with Uiso(H) = 1.5Ueq(O-hydroxyl, C-methyl) and 1.2Ueq(C) for other H atoms. The isopropyl group is disordered about two positions with a refined occupancy ratio of 0.763 (5):0.237 (5) for atoms C24–C27/C24B–C27B.

A region of disordered electron density was corrected for using the SQUEEZE routine in PLATON (Spek, 2015): volume ca 269 Å3 for 96 electrons count per There is possibly one molecule of diethyl ether per molecule of the title compound 2. The formula mass and unit-cell characteristics were not taken into account during refinement.

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. |
