In the title compound, C₂₈H₂₉NO₃, the fused pyrrolidine and piperidine rings of the octahydroindolizine unit exhibit envelope and chair conformations, respectively. The dihedral angle between the naphthalene ring system and the benzene ring is 40.37 (5)°. The crystal packing is stabilized by weak intermolecular C—H⋯O interactions.

Comment top

The synthesis of biologically active indolizine derivatives continues to attract the attention of organic chemists, because of their wide spectrum of biological activity. Indolizine derivatives have been found to possess a variety of biological activities such as antiinflammatory (Malonne et al., 1998), antiviral (Medda et al., 2003), aromatase inhibitory (Sonnet et al., 2000), analgestic (Campagna et al., 1990) and antitumor (Pearson & Guo, 2001) activities.

The geometric parameters of the title compound (Fig. 1) agree well with reported similar structures (Gunasekaran et al., 2009; Kamala et al., 2009). The mean plane of the naphthalene ring system makes a dihedral angle of 40.37 (5)° with the methyl benzene ring. In the molecule the pyrrolidine ring N1/C13/C12/C19/C18 exhibits an envelope conformation with envelope on C13 with an asymmetry parameter (Nardelli, 1983) ΔC_s (C13) = 14.17 (3) and with the puckering parameters (Cremer & Pople, 1975) q2 = 0.4960 (2) Å and ϕ2 = 205.68 (9)°. The six membered ring N1/C14—C18 exhibits chair conformation with asymmetry parameters ΔC_s (N1) = 1.78 (1)/(C16) = 1.78 (1) and with the puckering parameters Q = 0.5855 (2) Å, Θ = 3.86 (3)° and ϕ = 335.84 (8)°. The sum of bond angles around N1 [333.20 (12)°] indicates sp³ hybridization. The crystal packing is stabilized by weak intermolecular C—H···O interactions.

Experimental top

A mixture of (Z)-methyl 2-[(1-formylnaphthalen-2-yloxy)methyl]-3-tolylacrylate (20 mmol) and pipecolinic acid (30 mmol) were refluxed in benzene for 20 h and the solvent was removed under reduced pressure. The crude product was subjected to column chromatography to get the pure product. Chloroform and methanol (1:1) solvent mixture was used for the crystallization under slow evaporation method.

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.
