In the title compound, C24H17NO2, the carbonyl O atom of the benzoyl group is cis with respect to the furanyl O atom, and the associated O—C—C—O torsion angle is 4.62 (19)°. The puckering of the dihydrofuran ring is close to twisted (4T5), with parameters Q = 0.1856 (16) Å and φ = 313.5 (5)°. Molecules are interconnected via a C—H⋯N and a C—H⋯O hydrogen bond, leading to layers parallel to the (200) plane and characterized by R44(28) and R44(36) graph-set motifs. The furan O atom does not participate in intermolecular hydrogen bonding. The encompasses a solvent-accessible void of 24.7 (8) Å3.

The title compound 5-benzoyl-2,4-diphenyl-4,5-dihydrofuran-3-carbonitrile (I) is a dihydrofuran carbonitrile derivative. Dihydrofurans belong to an important class of heterocycles and are known for distinct insect antifeedant activities (Gebbinck et al., 1999). Dihydrofurans have also been found to possess antifungal (Pour et al., 2003) and anti-inflammatory properties (Kumar et al., 2003). The dihydrofuran derivatives with their reactive functional groups like methoxy, carbonyl etc. may prove to be promising candidates for the synthesis of novel
The in vitro antibacterial and antifungal activities of some furan derivatives, specifically, 4,5-dihydrofuran-3-carbonitriles were investigated against some bacteria and fungi and were found to show activity against bacteria better than some known antibiotics (Loğoğlu et al., 2010).A mixture of benzoylacetonitrile (1.0 mmol), benzaldehyde (1.0 mmol) and imidazolium salt (1-methyl-3-(2-oxo-2-phenylethyl)-1H-imidazol-3-ium bromide) (1.0 mmol) were dissolved in EtOH (10 mL) then Et3N(triethylamine) (1.0 mmol) was added slowly and refluxed on a water bath. The consumption of starting material was monitored by TLC. After 3hours the reaction mixture was cooled and the precipitated solid product was filtered and washed. Crystals of (1) suitable for diffraction were obtained.
All H atoms were included into the model at geometrically calculated positions (C—H target distance = 0.98 Å for methine H atoms and 0.93 Å for all other aromatic H atoms) and refined using a riding model. The Uiso values of all H atoms were constrained to 1.2 times Ueq of the respective atom to which the H atom binds.
The carbonyl O of the benzoyl group is cis with the furanyl O atom with the value of the associated torsion angle being 4.62°. The puckering of the hydrofuran ring is close to twisted (4T5) with parameters Q = 0.1856 (16) Å and φ = 313.5 (5)°. The angle between the mean plane about the furan ring atoms and the 2-phenyl ring is 22.5 (1)° while those with respect to the 4-phenyl and the 5-benzoyl group atoms are 88.6 (1) and 78.4 (1)°, respectively.
A search in the CSD [version 5.53, update 3, May 2013] for organic nonpolymeric single crystal structures for which 3D coordinates determined with no disorder, no ions and no other errors with R-factors less than 0.05 revealed 6287 structures of which 2498 had the furan O involved in C—H···O interactions with the H···A ranging from 2.127 to 2.720 Å. Also, four structures bearing close relationships to the title compound with refcodes LEFJUD (Suresh et al., 2012a), YAXGOV (Suresh et al., 2012b), ZARBEB (Suresh et al., 2012c) and EDUZAG (Rajni Rajni et al., 2012) were found. These structures differ by an indole ring replaced by a phenyl in the title compound and interestingly none display any change in the
or lattice type. However, there are drastic differences in the intermolecular interaction patterns. The molecules are interconnected via a C—H···N and a C—H···O hydrogen-bond leading to a layers parallel to the (200) plane and characterized by R44(28) and R44(36) graph-set motifs.

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. |
