The furan ring in the title compound, C₂₇H₂₀N₂O₂, adopts a twisted conformation about the sp³—sp³ bond. The molecular structure is stabilized by an intramolecular C—H⋯O interaction which generates an S(6) ring motif. The crystal packing is stabilized by N—H⋯O and C—H⋯O interactions generating centrosymmetric R₂²(18) and C(6) chain motifs, respectively. A weak C—H⋯π interaction is also observed.

Comment top

Furanyl derivatives have calplain-inhibiting activity and are used in the preparation of medicaments for the treatment of inflammatory and immunological diseases, cardiovascular and cerebro-vascular diseases, disorders of the central or peripheral nervous system, cachexia, osteoporosis, muscular dystrophy, proliferative diseases, cataracts, rejection reactions following organ transplants and auto-immune and viral diseases (Auvin et al., 2005). The high medicinal value of these compounds in conjunction with our research interests prompted us to synthesize and report the X-ray structure of the title compound.

In the title compound (Fig 1), the five-membered furanyl ring adopts a twisted conformation as evident from the puckering parameters (Cremer & Pople, 1975) Q = 0.192 (2) Å and φ = 129.0 (6)°. The five-(N2/C38/C31/C32/C37) and six-membered (C32—C37) rings in the indole group are planar, with a dihedral angle of 0.74 (1)° between them. The dihedral angle between the phenyl rings (C42—C47 and C51—C56) is 15.24 (1)°.

Fig. 2 shows the partial packing of molecules in the crystal structure. The C—H···O and N—H···O intermolecular interactions generate C₁¹(6) chain and centrosymmetric R₂²(18) motifs, respectively (Bernstein et al., 1995). In addition, there is a weak C—H···π interaction, viz, C34—H34···Cg1ⁱⁱ_,Table 1.

Experimental top

To a stirred mixture of 2-(1H-indole-3-carbonyl)-3-p-tolylacrylonitrile (1.0 molar eq.) and phenacylpyridinium bromide (1.0 molar eq.) in water (10 ml) was added drop wise triethylamine (0.25 molar eq.) at room temperature. The resulting clear solution, that slowly became turbid, was stirred at room temperature for 1 h. Then, the separated free flowing solid was filtered and washed with methanol (3 ml) to afford the title compound as a pale-yellow solid. The product thus obtained was recrystallized from an EtOH-EtOAc mixture (1:1 ratio v/v ml) to the give pure compound as pale-yellow crystals. Yield: 92%. M.pt: 502 K.

Special details top

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.
