Compound (I) was prepared in 80% yield by stirring an ethanol (30 ml) mixture comprising 4-chlorohypnone (0.02 mol), 5-methylfurfural (0.02 mol) and 10% NaOH (10 ml) for 3 h. Single crystals were obtailed by recrystallization of (I) from ethyl acetate at room temperature.
H atoms were positioned geometrically and allowed to ride on their parent atoms, with C—H distances of 0.93–0.96 Å, and with Uiso(H) = 1.2–1.5Ueq(C).
Among
have been identified as interesting compounds with multiple biological actions, including anti-inflammatory (Hsieh et al., 1998) and anti-oxidant (Anto et al., 1994) activities. Of particular interest is the effectiveness of against cancer (De Vincenzo et al., 2000; Dimmock et al., 1998). As part of our search for new biologically active compounds, we synthesized the title chalcone, (I), and report its herein.The molecular structure of (I), Fig. 1, comprises a furan ring and a chlorophenyl group. These groups are not co-planar as seen in the value of the dihedral angle between them of 7.71 (2)°. Bond distances and angles conform to literature precedents (Guo, et al., 2008). There are intre- and inter-molecular C—H···O interactions that stabilize the molecular and crystal structures, respectively (Table 1). The intermolecular contacts lead to the formation of centrosymmetric dimers.

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. |

Among flavonoids, chalcones have been identified as interesting compounds with multiple biological actions, including anti-inflammatory (Hsieh et al., 1998) and anti-oxidant (Anto et al., 1994) activities. Of particular interest is the effectiveness of chalcones against cancer (De Vincenzo et al., 2000; Dimmock et al., 1998). As part of our search for new biologically active compounds, we synthesized the title chalcone, (I), and report its crystal structure herein.
The molecular structure of (I), Fig. 1, comprises a furan ring and a chlorophenyl group. These groups are not co-planar as seen in the value of the dihedral angle between them of 7.71 (2)°. Bond distances and angles conform to literature precedents (Guo, et al., 2008). There are intre- and inter-molecular C—H···O interactions that stabilize the molecular and crystal structures, respectively (Table 1). The intermolecular contacts lead to the formation of centrosymmetric dimers.
