The title compounds, C₃₈H₄₈O₁₁ (A and B), are tetracyclic benzoates composed of a taxane ring with a fused dioxolane ring as the core skeleton. In compound A, the five-membered dioxolane ring is essentially planar while the two cyclohexane rings and the cyclooctane ring adopt chair and chair–chair forms, respectively, and there are three intramolecular H⋯H short contacts. The corresponding ring conformations in B are similar; however, one intramolecular C—H⋯O interaction and two H⋯H short contacts are observed, and the benzoyl and methoxymethyl groups show orientational disorder. In the crystal of A, a pair of intermolecular O—H⋯O hydrogen bonds link two molecules into an inversion dimer, and weak intermolecular C—H⋯O interactions connect the dimers, forming a three-dimensional network. In the crystal of B, an inversion dimer is similarly generated by a pair of intermolecular O—H⋯O hydrogen bonds, and weak intermolecular C—H⋯O and C—H⋯π interactions connect the dimers into a three-dimensional architecture.

Keywords: crystal structure; hydrogen bond; taxane skeleton; paclitaxel; disorder.

1. Chemical context

Paclitaxel (systematic name: (1S,2S,3R,4S,7R,9S,10S,12R,15S)-4,12-diacetoxy-1,9-dihydroxy-15-{[(2R,3S)-3-benzoylamino-2-hydroxy-3-phenyl]propanoyl}oxy-10,14,17,17-tetramethyl-11-oxo-6-oxa-tetracyclo[11.3.1.0^3,10.0^4,7]heptadec-13-en-2-yl benzoate) is a well-known natural diterpenoid containing a taxane skeleton (tricyclo[9.3.1.0^3,8]pentadecane; Fig. 1), and exerts potent antitumour activity (Wall & Wani, 1995 ). Its complicated and highly functionalized structure with remarkable bioactivity has inspired immense chemical and medicinal interest. The title compounds, which are C-13 epimers of one another, were afforded in a synthetic study of paclitaxel (Fukaya et al., 2015a ,b , Iiyama, et al., 2022 ). Previously, several closely related structures (Oishi et al., 2015a ,b , 2021 ) have been reported (see Section 4).

2. Structural commentary

The molecular structures of the title compounds (A) and (B) are shown in Figs. 2 and 3, respectively. These conformations are similar except for the acetoxy group (Fig. 4): three H⋯H short contacts are observed in the structure (A), however the intramolecular C—H⋯O interaction is generated by the etheric O atom of the acetoxy group in (B) and one short contact has disappeared.

2.1. Compound A

The 1,3-dioxolane ring (C1/C2/O20/C21/O22) is essentially planar with a maximum deviation of −0.018 (2) Å for atom C1. The cyclohexane ring (C3–C8) adopts a chair form with puckering parameters Q = 0.559 (2) Å, θ = 8.6 (2)°, φ = 231.6 (15)°, Q(2) = 0.082 (2) Å and Q(3) = 0.553 (2) Å. The larger substituents (C3—C2, C7—O24 and C8—C9) are in equatorial positions, whereas the methoxymethoxy group (C4—O46) is tilted from the ideal equatorial position with a dihedral angle of 57.53 (11)° to the Cremer & Pople (1975 ) plane. Another cyclohexane ring (C1/C14/C13/C12/C11/C15) also adopts a chair form with puckering parameters Q = 0.535 (2) Å, θ = 168.6 (2)°, φ = 108.4 (12)°, Q(2) = 0.104 (2) Å and Q(3) = −0.524 (2) Å. Owing to the syn-fused ring system, the sterically more hindered substituents (C1—C2 and C11—C10) and hydroxy group (C12—O45) are in axial positions, while the benzyloxy group (C13—O37) is slightly tilted from the ideal equatorial position with angle to the Cremer & Pople plane of 59.55 (10)°. The central cyclooctane ring (C1–C3/C8–C11/C15) adopts a chair–chair form with puckering parameters Q = 0.862 (2) Å, Q(2) = 0.170 (2) Å, φ(2) = 115.3 (7)°, Q(3) = 0.108 (2) Å, φ(3) = 3.9 (11)° and Q(4) = 0.838 (2) Å. Unusual sp³ angles are observed at atoms C9 and C10 by strained ring system, with 125.07 (16)° for C8—C9—C10 and 124.29 (17)° for C9—C10—C11. There are intramolecular short contacts between atoms H2⋯H16C, H3⋯H13 and H9B⋯H13 with distances of 1.81, 1.94 and 1.97 Å, respectively (Fig. 4).

2.2. Compound B

The 1,3-dioxolane ring (C1/C2/O20/C21/O22) is essentially planar with a maximum deviation of −0.014 (2) Å for atom C2. The cyclohexane ring (C3–C8) adopts a chair form with puckering parameters Q = 0.573 (2) Å, θ = 6.9 (2)°, φ = 241.3 (19)°, Q(2) = 0.068 (2) Å and Q(3) = 0.569 (2) Å. The larger substituents (C3—C2, C7—O24 and C8—C9) are in equatorial positions, while the methoxymethoxy group (C4—O46) is tilted slightly from the ideal equatorial position with a dihedral angle to the Cremer & Pople plane of 58.95 (14)°. Another cyclohexane ring (C1/C14/C13/C12/C11/C15) also adopts a chair form with puckering parameters Q = 0.556 (2)Å, θ = 167.1 (2)°, φ = 110.0 (10)°, Q(2) = 0.124 (2) Å and Q(3) = −0.542 (2) Å. Similar to compound A, the sterically more hindered substituents (C1—C2 and C11—C10) and hydroxy group (C12—O45) are in axial positions because of the syn-fused ring system, while the benzyloxy group (C13—O37) is in an equatorial position. The central cyclooctane ring (C1–C3/C8–C11/C15) adopts a chair–chair form with puckering parameters Q = 0.825 (2) Å, Q(2) = 0.161 (2) Å, φ(2) = 113.9 (8)°, Q(3) = 0.166 (2) Å, φ(3) = 17.2 (8)° and Q(4) = 0.792 (2) Å. Atypical sp³ angles are observed at atoms C9 and C10 of the ring system, which is strained more than in compound A, with 128.84 (17)° for C8—C9—C10 and 127.33 (19)° for C9—C10—C11. The molecular conformation is supported by an intramolecular C—H⋯O hydrogen bond (C2—H2⋯O33), generating an S(7) graph-set motif. There are two intramolecular short contacts between the atoms H2⋯H16C and H3⋯H13, with distances of 1.80 and 1.92 Å, respectively. The H9B⋯H13 short contact is not observed, the distance being 2.03 Å.

The benzoyl group (C25/O26/C27–C32) is disordered over two orientations, with refined occupancies of 0.499 (3) and 0.501 (3). The methoxymethyl group (C47/O48/C49) is also disordered over two sites, with refined occupancies of 0.495 (4) and 0.505 (4).

3. Supramolecular features

3.1. Compound A

In the crystal, pairs of intermolecular O—H⋯O hydrogen bonds (O45—H45⋯O35ⁱ; symmetry code as given in Table 1), generating an R₂²(16) graph-set motif, form inversion dimers (Fig. 5). The dimers are linked by weak intermolecular C—H⋯O interactions (C38—H38A⋯O24ⁱⁱ; Table 1) extending a tape structure running along the a-axis direction. The tapes are further connected by weak intermolecular C—H⋯O interactions (C19—H19B⋯O23ⁱⁱⁱ and C29—H29⋯O33^iv; Table 1, Fig. 6) into a three-dimensional network. In addition, an intermolecular π–π interaction (Cg1⋯Cg1^iv; depicted as overlapped rings at the corners of the unit cell in Fig. 6, where Cg1 is the centroid of the C27–C32 benzene ring) is also observed with a centroid–centroid distance of 3.7051 (15) Å.

3.2. Compound B

The crystal packing also features pairs of intermolecular O—H⋯O hydrogen bonds (O45—H45⋯O35ⁱ; Table 2) with an R₂²(16) graph-set motif, forming inversion dimers (Fig. 7). Pairs of intermolecular C—H⋯O interactions (C18—H18C⋯O45ⁱ; Table 2) support the dimer formation, with an R₂²(8) graph-set motif. The dimers are linked by intermolecular C—H⋯O interactions (C38—H38A⋯O24ⁱⁱ and C32D—H32D⋯O37ⁱⁱⁱ; Table 2), elongating a tape structure running along the a-axis direction. Adjacent tapes are further connected through weak intermolecular C—H⋯O and C—H⋯π interactions (C19—H19A⋯O23^iv and C28D—H28D⋯Cg2^v; Table 2, Fig. 8) into a three-dimensional architecture.

4. Database survey

In the Cambridge Structural Database (CSD, Version 5.45, September 2024; Groom et al., 2016 ), 106 structures containing a tricyclo[9.3.1.0^3,8]pentadecane (taxane) core, (a), are deposited (Fig. 9). These include two chiral compounds [CSD refcodes OACBRT10 (Shiro & Koyama, 1971 ) and ZOPNUN (Kelly et al., 1996 )], possessing a 10-acetoxy-8,12,15,15-tetramethyltaxane skeleton, (b). The ring conformations of the taxane framework [upper, cyclohexane (U), middle, cyclooctane (M) and lower, cyclohexane, (L)] in the former structure are slightly skewed boat, boat–chair and chair forms, respectively, while those in the latter are chair, twist–boat–chair and half-chair, respectively. The relative stereochemistries at the C-13 acetoxy groups in both compounds are coincident with that of compound B.

Figure 9

Ring-fusion geometries in the related structures are similar to the title compound, as syn-UM and anti-ML.

Another search for a saturated tetracyclic core related to the title compound, (c), gave no entries, whereas its 15-ene (d), 14-ene (e) and 14,16-diene (f) derivatives, afforded in our synthetic studies, are available [XULNAV, XULMOI and XULMUO (Oishi et al., 2015a), PAJKEU (Oishi et al., 2021) and GUHMUD (Oishi et al., 2015b)].

5. Synthesis and crystallization

The title compounds were obtained in the synthetic study of paclitaxel (Fukaya et al., 2015a,b). The precursor of the cyclohexane unit (C1/C14/C13/C12/C11/C15), prepared according to the reported procedure (Nicolaou et al., 1995 ), were coupled with the substituted cyclohexane unit (C3–C8) derived from 3-methylanisole by a Shapiro reaction (Nicolaou et al., 1995). A cyclization reaction generated the central cyclooctane, and further manipulations of the functional groups gave a mixture of tetracyclic benzoates A and B. Separation and purification were carried out by silica gel chromatography. Colourless crystals of A suitable for X-ray diffraction were grown from a benzene solution under a pentane-saturated atmosphere by slow evaporation at ambient temperature. In a similar manner, colourless crystals of B were also obtained.

6. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 3. C-bound H atoms were positioned geometrically with C—H = 0.95–1.00 Å, and constrained to ride on their parent atoms with U_iso(H) = 1.2U_eq(C) or 1.5U_eq(methyl C). The H atom of the hydroxy group was located in a difference map, and treated as riding with O—H = 0.84 Å and U_iso(H) = 1.5U_eq(O). One problematic reflection for A and four reflections for B were omitted in the final cycles of 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.

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 > 2σ(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.

Model structure was improved by utilizing the BUMP command to solve the intramolecular short contact of 1.78 Å between atoms H2 and H16C. Problematic reflection with |I(obs)–I(calc)|/σW(I) greater than 10 (0 –1 1) have been omitted in the final refinement.

Model structure was improved by utilizing the BUMP command to solve the intramolecular short contact of 1.78 Å between atoms H2 and H16C, and the RIGU commands to estimate U values of the disordered benzene ring. Problematic 4 reflections with |I(obs)–I(calc)|/σW(I) greater than 10 (0 10 7, 2 6 11, 0 1 1 and 2 –1 1) have been omitted in the final refinement.
