Crystal structures of three newly synthesized flavanone hydrazones

The crystal structures of racemic mixtures of three new flavanone-hydrazones are reported: (±,E)-N′-[5,7-dihy­droxy-2-(4-hy­droxy­phen­yl)chroman-4-yl­idene]-2-(naphthalen-1-yl)acetohydrazide ethyl acetate monosolvate, (±,E)-N′-[5,7-dihy­droxy-2-(4-hy­droxy­phen­yl)chroman-4-yl­idene]-4-hy­droxy­benzohydrazide ethanol monosolvate and (±,E)-N′-(6-meth­oxy-2-phenyl­chroman-4-yl­idene)-2-(naphthalen-1-yl­oxy)acetohydrazide. All three hydrazones are in the E isomeric form and exhibit a pucker at the chiral carbon atom. The naringenin-derived hydrazones both show intra­molecular hydrogen bonding between the hydrazone nitro­gen atom and a hy­droxy group on the chromane ring.

Abstract

The crystal structures of racemic mixtures of three new flavanone-hydrazones in the centrosymmetric space group (P ), are reported. The structures of (±,E)-N′-[5,7-dihy­droxy-2-(4-hy­droxy­phen­yl)chroman-4-yl­idene]-2-(naphthalen-1-yl)acetohydrazide ethyl acetate monosolvate, C₂₇H₂₂N₂O₅·C₄H₈O₂, and of (±,E)-N′-[5,7-dihy­droxy-2-(4-hy­droxy­phen­yl)chroman-4-yl­idene]-4-hy­droxy­benzo­hydra­zide ethanol monosolvate, C₂₂H₁₈N₂O₆·C₂H₅OH, both exhibit an intra­molecular O—H⋯N and multiple inter­molecular O—H⋯O and C—H⋯O-type hydro­gen bonds. The third structure, that of (±,E)-N′-(6-methoxy-2-phenyl­chroman-4-yl­idene)-2-(naphthalen-1-yl­oxy)acetohydrazide, C₂₈H₂₄N₂O₄, has only one inter­molecular N—H⋯O-type hydrogen bond. In each of the three cases, the crystal packings are stabilized by π–π stacking inter­actions between various aromatic components of symmetry-related mol­ecules. The chiral carbon atom of the substituted chromane ring system in each case is puckered away from rest of the ring system.

1. Chemical context

Flavonoids encompass a family of organic, naturally occurring polyphenolic compounds with a general structure consisting of a 15-carbon skeleton containing two phenyl rings and a heterocyclic ring. Flavonoids include various subcategories – chalcones, flavones, flavanones, flavanols, isoflavones, anthocyanins – all of which have demonstrated differential health benefits such as anti-­oxidative, anti-inflammatory, anti-mutagenic, and anti-carcinogenic properties (Panche et al., 2016 ▸). As a result of their biologically privileged scaffold, flavonoids and their synthetic derivatives are of significant inter­est to the medicinal chemistry community as potential treatments of disease. We recently reported the first crystal structure of a hydrazone derivative of naringenin, (R/S,E)-2-(4-hy­droxy­phen­yl)-4-(2-phenyl­hydrazineyl­idene)chromane-5,7-diol, a biologically active compound that has been reported to induce apoptosis in human cervical cancer cells (Yennawar & Sigmon, 2022 ▸; Kim et al., 2012 ▸). To further explore the medicinal potential of this class of compounds, three new flavonoid hydrazone compounds have been synthesized and structurally characterized. The three novel compounds are: (±,E)-N′-[5,7-dihy­droxy-2-(4-hy­droxy­phen­yl)chroman-4-yl­idene]-2-(naphthalen-1-yl)acetohydrazide ethyl acetate monosolvate (I), (±,E)-N′-(5,7-dihy­droxy-2-(4-hy­droxy­phen­yl)chroman-4-yl­idene)-4-hy­droxy­benzohydrazide ethanol monosolvate (II) and, (±,E)-N′-(6-meth­oxy-2-phenyl­chroman-4-yl­idene)-2-(naphthalen-1-yl­oxy)-acetohydrazide (III).

2. Structural commentary

Each of the three title compounds (Figs. 1 ▸, 2 ▸ and 3 ▸) has a carbon–nitro­gen double bond [N1=C1: 1.291 (3), 1.294 (4) and 1.284 (5) Å] and all are in the E isomeric form. The pyran ring of the chromane ring system in each structure has an envelope pucker with values of the puckering amplitude Q of 0.423 (3), 0.397 (6), 0.331 (5) Å, and of θ = 57.9 (4), 53.9 (6), 58.1 (7)°, respectively. The chiral carbon (C8) in each case is displaced between 0.454 and 0.580 Å from the chromane ring planes. The puckering is similar to that seen in the previously reported structure (Yennawar & Sigmon, 2022 ▸).

In compound I, the disordered fractions (65/35%) of the 4-hy­droxy­phenyl ring makes dihedral angles of 77.128 (5) and 83.872 (5)°, respectively, with the chromane ring system. An intra­mol­ecular O—H⋯N hydrogen bond exists between one of the hy­droxy groups on the chromane ring and the nitro­gen of the hydrazone group [O—H⋯N = 2.527 (2) Å, 147°]. Another hy­droxy group on the chromane ring participates in a hydrogen bond with the carbonyl group of the solvent ethyl acetate mol­ecule [O2—H2⋯O6 = 2.720 (3) Å, 173°]. The naphthalene ring system is close to perpendicular to the chromane ring system [dihedral angle 77.692 (5)°].

In II, the 4-hy­droxy­phenyl ring of the hydrazone moiety is coplanar with the chromane ring [dihedral angle of 2.485 (3)° with the chromane ring system] whereas the other hy­droxy­phenyl ring is almost perpendicular [75.449 (5)°] to the chromane ring system. The chiral carbon of chromane ring (C8_1) and the methyl carbon (C2_1) of the solvent mol­ecule show positional disorder. An intra­mol­ecular O—H⋯N hydrogen bond exists between one of the hy­droxy groups on the chromane ring and the nitro­gen of the hydrazone group [O3—H3⋯N1 = 2.542 (3) Å, 147°].

In III, the phenyl ring makes a dihedral angle of 86.17 (1)° with the chromane ring system, while the naphthalene ring system is perpendicular to the chromane ring system [dihedral angle = 89.65 (1)°].

3. Supra­molecular features

The extended packing of both I and II (Figs. 4 ▸ and 5 ▸) exhibit inter­molecular O—H⋯O and C—H⋯O-type inter­actions. Additionally II has N—H⋯O-type inter­actions (Tables 1 ▸ and 2 ▸). Both these packings have solvent mol­ecules, namely ethyl acetate and ethanol, respectively, which inter­act with the parent mol­ecules via O—H⋯O-type hydrogen bonds. In I, π–π inter­actions between the chromane rings of symmetry-related neighbors in the [101] direction are observed. The hy­droxy­phenyl rings also show similar stacking with their symmetry-related counterparts along the [10 ] direction. Partial stacking (π–π) inter­actions [centroid–centroid distance = 4.51 (1) Å] are observed between the chromane unit and the 4-hydroxyphenyl ring of the hydrazone moiety.

In III (Fig. 6 ▸) the hydrogen-bond inter­action is limited to one N—H⋯O-type hydrogen bond between the hydrazone group and carbonyl oxygen of a symmetry-related neighbor [N2—H2⋯O3 = 2.922 (4) Å, 167°], in a parallel, mutual give-and-take fashion (Table 3 ▸). Parallel, partial stacking between symmetry-related naphthalene rings [centroid–centroid distance = 3.790 (2) Å], and also between the chromane ring system and the hydrazone group of neighboring mol­ecules [centroid–centroid distance = 3.730 (3) Å] further stabilizes the packing.

4. Database survey

A structure search was performed in Scifinder and Reaxys, and no identical structures were found. A text search (‘flavanone’ and ‘chroman-4-yl­idene’ and ‘chromane-5,7-diol’ and ‘benzo­pyran-4-yl­idene’ and ‘chromen-4-yl­idene’) was performed in the CCDC’s free Access Structures online database (Groom et al., 2016; accessed January, 2023 ▸). Six structures were found of hydrazone derivatives of flavanones, including our previously reported naringenin derivative (Yennawar & Sigmon, 2022 ▸). No crystal structures were found of flavanone hydrazones containing a naphthalene moiety. Examples of other flavanone hydrazones for which crystal data have been reported include acyl hydrazone derivatives of 2-phen­ylchroman-4-one and hesperetin. In particular, crystal structures for 2′-[2-(4-fluoro­phen­yl)­chroman-4-yl­idene]iso­nico­tinohydrazide (Nie et al., 2006 ▸) and N-{(±)-[5,7-di­hy­droxy-2-(3-hy­droxy-4-meth­oxy-phen­yl)­chroman-4-yl­idene]am­ino}­benzamide (Lodyga-Chruscinska et al., 2015 ▸) have been reported.

5. Synthesis and crystallization

For the preparation of I, naringenin (653 mg, 2.4 mmol) and 2-(naphthalen-1-yl)acetohydrazide (501 mg, 2.5 mmol) were dissolved in ethanol (10 mL). Acetic acid (2.4 mmol, 137 µL) was added and the resultant solution was heated at reflux for 21 h. The precipitate was isolated via vacuum filtration and recrystallized from ethyl acetate via slow evaporation at room temperature to furnish clear, plate-shaped crystals suitable for X-ray analysis.

For the preparation of II, naringenin (3.000 g, 11.02 mmol) and 4-hy­droxy­benzohydrazine (2.011 g, 13.22 mmol) were dissolved in ethanol (20 mL). Acetic acid (17.5 mmol, 1.0 mL) was added and the resultant solution was heated at reflux for 48 h. The precipitate was isolated via filtration and recrystallized from ethanol via slow evaporation at room temperature to furnish transparent yellow, plate-shaped crystals suitable for X-ray analysis.

For the preparation of III, 6-meth­oxy­flavanone (381 mg, 1.5 mmol), 2-(naphthalen-1-yl)acetohydrazide (356.8 mg, 1.1 eq, 1.65 mmol), and p-toluene­sulfonic acid (29 mg, 0.10 eq, 0.15 mmol) were dissolved in toluene (15mL). The resultant mixture was heated at reflux for 12 h with a Dean–Stark apparatus. The solvent was removed and the crude product was purified on an automated flash chromatography system using a normal phase silica gel column with a gradient of hexa­ne:ethyl acetate (70:30 to 0:100). Recrystallization of the purified compound from ethanol via slow evaporation at room temperature furnished yellow, needle-shaped crystals suitable for X-ray analysis.

6. Refinement

Crystal data, data collection and structure refinement details for all three structures are summarized in Table 4 ▸. The hydrogen atoms were placed in their geometrically calculated positions and their coordinates refined using the riding model with parent-atom—H lengths of 0.93 Å (CH), 0.98 Å (chiral-CH), 0.96 Å (CH₃), 0.97 Å (CH₂), 0.86 Å (NH) or 0.82 Å (OH). Isotropic displacement parameters for these atoms were set to 1.2 (CH, NH) or 1.5 (CH₃, OH) times U _eq of the parent atom. In II, the positional disorder of the chiral carbon (C8) and phen­oxy ring atoms (C10 through C15) refined to a percentage population ratio of 66/34, and that of the solvent (ethanol) mol­ecule to 57/43, necessitating the use of a total of 136 restraints. The idealized Me of the ethanol mol­ecule were refined as rotating group(s): C2_3 and C2_4 (H2A_3 through H2C_4).

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.

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.

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.
