(Received 6 December 2011; accepted 23 December 2011; online 7 January 2012)

In the title compound, C₂₂H₂₃N₃O₄, the tolyl ring is almost perpendicular [83.86 (7)°] to the best plane through the eight atoms of the pyrrolizidine ring system. The molecular conformation is stabilized by an intramolecular O—H⋯O hydrogen bond. The crystal packing features inversion dimers with R₂²(8) motifs linked by pairs of N—H⋯O hydrogen bonds.

Comment top

The indole unit is observed in plants (Nigović et al., 2000). Some of the indole derivatives exhibit anti-tumour (Schollmeyer et al., 1995) and anti-bacterial (Okabe & Adachi,1998) activities. Sumatriptan, an indole derivative has been introduced into medicine as a drug for the treatment of migraine (Oxford, 1995). Pyrido [1, 2 - a]indole derivatives have been observed as potent inhibitors of HIV-typeI (Taylor et al., 1999). Spiro-indoles have been reported to exhibit fungicidal activity(Ali et al., 1989). In view of the wide spectrum of biological activity of indole and pyrrolizidine derivatives, the X-ray analysis of the title compound has been undertaken and the crystallographic details are reported in this communication. Bond lengths and bond angles of the pyrrolizidine group and the indole unit are in the same range as observed in reported structures (Usha et al., 2005) The C7 = O4 double bond is slightly elongated [1.225 (2) Å] and this may be due to the active involvement of O4 both in intra and intermolecular hydrogen bonding. The pyrrolizidine ring is perpendicular to the methyl benzyl ring [89.8 (1)°]. The pyrrolizidine and methyl benzyl ring make angles of 81.7 (1) and 68.9 (1)°, respectively, with the oxindole system. The sum of the angles around N2 and N3 [360 and 341.7°], indicates sp² and sp³ hybridization, respectively. The N3/C11—C14 ring adopts a half chair conformation with the smallest asymmetry parameter (Nardelli, 1983) of D2 (N3) = 0.018 (1)°. The asymmetry parameter DS (C9)= 0.024 (1)° indicates the half chair conformation of the N3/C8/C9/C15/C14 ring. The overall conformation of the pyrrolizidine ring is folded about the bridging bond N3—C14. In the title compound, each molecule is linked to two of its adjacent centro-symmetrically related molecules through N—H···O and C—H···O hydrogen bonds, forming dimers described by R²₂(8) and R²₂(18) rings. The atom O3 acts as a donor for an intrammolecular hydrogen bond.

Experimental top

A mixture of (E)-2- nitro-3-p-tolylprop-2-en-1-ol(2 mmol, 0.39 g),isatin(2 mmol, 0.29 g)and l-proline (2 mmol, 0.23 g) in acetonitrile(8 ml) was refluxed for 2 h. After the completion of the reaction as indicated by TLC, the reaction mixture was concentrated and the resulting crude mass was diluted with water (20 ml) and extracted with ethyl acetate (3x10ml) and dried over anhydrous NaSO4 The organic layer was concentrated and purified by column chromatography on silica gel (Acme 100–200 mesh), usingethyl acetate: hexanes (3:7) to provide as a colorless solid in 59% (0.46 g)yield.

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.
