Abstract top

In the title E isomer of the racemic compound, C37H32F2N2O2, the pyridinone ring adopts a twisted half-chair conformation with the N atom deviating by -0.355 (3) Å and with the methylene C atom next to octahydroindolizine moiety deviating by 0.415 (3) Å from the mean plane defined by other four atoms. In the octahydroindolizine system, the pyrrolidine ring exhibits an envelope conformation with the fused methyne C atom deviating by 0.6496 (1) Å from the mean plane defined by four other atoms, and the piperidine ring exhibits a distorted chair conformation as evident from the puckering parameters Q = 0.568 (2) Å, [theta] = 1.0 (2) and [Phi] = 256 (11)°. In the crystal, C-H...O interactions connect the molecules into chains along [101].

Comment top

Indolizine derivatives have been found to possess a variety of biological activities such as anti-inflammatory (Malonne et al., 1998), antiviral (Medda et al., 2003) and anti-tumor (Pearson & Guo, 2001) activities. In view of its medicinal importance and in conjunction with our research interests, we synthesized the title compound and report here its X-ray structure.

In the title compound (Fig.1), the pyridinone ring adopts twisted half chair conformation with atoms N2 and C2 deviating by -0.355 (3)Å and 0.415 (3)Å respectively, from the mean plane defined by other atoms C3/C4/C5/C6. The sum of bond angles around N2 (332.65 (1) °) indicates a pyramidal geometry. Although the atoms C1, C2, C6 attached to the atom N2, are all in Sp2 hybridization, their different environments cause differences in bond lengths (N2-C2 (1.4467 (19) Å) and N2-C6 (1.457 (2) Å)) and in the bond angles (C1-N2-C2 (112.35 (13) °), C1-N2-C6 (111.00 (14) °) and C2-N2-C6 (109.31 (12) °)). The methyl group at position 1 of the pyridinone ring is in equatorial orientation, denoted by the torsion angle C1-N2-C6-C5 (177.38 (1) °). In the fused system , the pyrrolidine ring adopts the twisted envelope conformation with C8 atom at the flap deviating by 0.6496 (1) Å from the mean plane defined by other atoms C7/C3/C13/N1 and this orientation may be due to the intra-molecular C7—H7···O1 interaction. In the fused system the piperidine ring adopts a slightly distorted chair conformation as evident from the puckering parameters Q = 0.568 (2) Å, θ = 1.0 (2)° and Φ = 256 (11)° (Cremer & Pople, 1975). The twist of the 4-fluorobenzene ring (C52-C57) with respect to the spiro junction is denoted by the torsion angle C5-C51-C52-C57 (-49.1 (2) °). The dihedral angle between the mean plane of the pyridinone ring, defined by the atoms C2/C4/C5/C6 with the two 4-fluorobenzene rings are 87.70 (1) ° and 63.20 (1)°. The carbonyl bond length, i.e C4=O1 (1.214 (2) Å), is somewhat longer, due to C—H···O contacts. The C8—N1 bond length (1.456 (2) Å) is comparable with the CSp2—NSp2 distance found in similar structures (Sussman & Wodak, 1973; Wodak, 1975).

The structure is stabilized by intermolecular C11—H11A···O1 interactions generating chains along [101] (Fig. 2).

Experimental top

A mixture of 1-methyl-3,5-bis[(E)-4-fluromethylidene]tetrahydro-4(1H)- pyridinone (1 mmol), acenaphthenequinone (1 mmol) and piperidine-2- carboxylic acid (1 mmol) was dissolved in isopropyl alcohol (15 ml) and heated to reflux for 60 min. After completion of the reaction, as evident from TLC, the mixture was poured into water (50 ml), the precipitated solid was filtered and washed with water (100 ml) to obtain pure yellow solid. Melting point:498 K, Yield: 93%

Refinement top

H atoms were placed at calculated positions and allowed to ride on their carrier atoms with C—H = 0.93–0.98 Å; Uiso = 1.2Ueq(C) for CH2 and CH groups, and Uiso = 1.5Ueq(C) for CH3 groups. The (0 1 1) reflection was probably affected by the beam-stop and was omitted from the refinement.

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 > 2σ(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.
