6-Butyryl-5-hy­droxy-4-phenyl­seselin

Abstract

In the title coumarin compound (systematic name: 6-butyryl-5-hy­droxy-8,8-dimethyl-4-phenyl-2H,8H-benzo[1,2-b;3,4-b′]dipyran-2-one), C24H22O5, also known as mammea A/AC cyclo D, the chromene and pyran rings are almost coplanar with a maximum deviation from the mean plane of 0.295 (2) Å. The attached phenyl group is inclined at 53.49 (8)° with respect to the chromene ring. The mol­ecular structure is stabilized by an intra­molecular O—H(...)O hydrogen bond. In the crystal, mol­ecules are linked into sheets parallel to (101) by inter­molecular C—H(...)O hydrogen bonds. Adjacent sheets are sustained by inter­molecular C—H(...)π and π–π [centroid–centroid distance = 4.471 (2) Å] inter­actions.

Comment

The title coumarin compound, 6-butyryl-5-hydroxy-4-phenylseselin or mammea A/AC cyclo D (Fig. 1) was isolated from the hexane crude extract of the flowers of Mammea siamensis (Sarapee in Thai). Several coumarins derived from the same flowers have been reported, see for example Mahidol et al. 2002 and other references cited therein. In this work, we report the crystal structure of mammea A/AC cyclo D.

The molecular structure consists of one chromene ring, one pyran ring and one phenyl ring (Fig. 1). The chromene and pyran rings are almost coplanar. Atoms C2, C2", C4" and O1" most deviate from the mean plane by 0.133 (3), 0.295 (2), –0.154 (3) and –0.172 (2) Å, respectively. The butyraldehyde group, hydroxy group and atom O2 displace from the chromene plane to greater extents: 0.326 (3) Å, O3; 0.307 (4) Å, O1"'; and –0.303 (7) Å, C3"'. The methyl C4"', C5" and C6" atoms point upwards and downwards the chromene ring with torsion angles of –73.8 (6)° for C1"'—C2"'—C3"'—C4"', –142.8 (3)° for C4"—C3"—C2"—C5" and 91.7 (4)° for C4"—C3"—C2"—C6". The attached phenyl group inclines by 53.49 (8)° against the chromene ring. The molecular structure is stabilized by intramolecular O3—H···O1"' hydrogen bond.

In the crystal, the molecules are linked into sheets parallel to (101) by intermolecular, bifurcated C3"'—H32···O2(x, y + 1, z) and C4'—H4'···O2(x – 0.5, –y + 0.5, z + 0.5) hydrogen bonds (Fig. 2 and Table 1). The adjacent sheets are sustained by intermolecular C6"—H61"···π (ring C1'—C2'—C3'—C4'—C5'—C6') and π–π (two adjacent rings of C4a—C5—C6—C7—C8—C8a) interactions (Fig. 3). The corresponding distance from atom H to the phenyl-ring center is 2.75 Å and the interplanar spacing is 3.54 Å.

Experimental

The title coumarin compound was isolated from the hexane crude extract of the flowers of Mammea siamensis, which is a Thai medicinal plant, locally known as Sarapee. This coumarin mammea A/AC cyclo D was known for almost 30 years. Its structure was ambigously characterized by spectroscopic techniques (Thebtaranonth et al., 1981; Morel et al., 1999; and Kaweetripob et al., 2000). Other coumarins were also isolated from the same flower (Mahidol et al., 2002 and other references cited therein).

The light yellow, block-like single crystals were obtained by slow evaporation of a hexane–dichloromethane solution at room temperature.

Refinement

All H atoms were located in a difference Fourier map and then refined using a riding model: C–H = 0.97 Å(secondary), 0.93 Å (aromatic), 0.96 Å (methyl), O–H = 0.82 Å (hydroxy), and Uiso(H) = 1.2Ueq(C,O) and Uiso(H) = 1.5Ueq(methyl C). In the absence of significant anomalous scattering effects, Friedel pairs were averaged and therefore, the absolute structure could not be determined.

Special details

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.
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 > σ(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.
