In the title compound, C31H32N2O6·H2O, the pyrrolidine ring adopts an The ethyl C atoms of the ethoxycabonyl group are disordered over two positions with occupancies of ca 0.80 and 0.20. Intramolecular N—H⋯O hydrogen bonds form S(5) and S(6) ring motifs. Molecules are linked into a three-dimensional framework by O—H⋯O, N—H⋯O and C—H⋯O hydrogen bonds, and by C—H⋯π interactions.

3-Arylidene-4-vinylindoline-2-one (0.5 g, 1.0 mol) and (E)-ethyl-2-(3,4,5-trimethoxybenzylideneamino)acetate (0.15 g, 1.0 mol) in acetonitrile (10 ml) was stirred in the presence of catalytic amount of AgOAc and triethylamine. The obtained crude product was recrystallized in n-hexane-acetone (8:2 v/v).
The ethyl C atoms of the ethoxycarbonyl group are disordered over two positions (C7/C7A and C8/C8A) with refined occupancies of 0.797 (8) and 0.203 (8). The corresponding bond distances involving the disordered atoms were restrained to 1.54 (5) Å, and also the Uij parameters of atoms C7, C7A, C8 and C8A were restrained to an approximate isotropic behaviour. The O– and N-bound H atoms were located in a difference map and refined with O—H and H···H distances restrained to 0.84 (1) and 1.37 (1) Å, respectively. The remaining H atoms were positioned geometrically (C—H = 0.93–0.98 Å) and allowed to ride on their parent atoms, with Uiso(H) = 1.2–1.5(methyl) Ueq(C). A search for solvent-accessible voids in the
using PLATON showed a potential solvent volume of 2189.3 Å3 and subsequent application of SQUEEZE procedures showed three relevant voids each with a solvent-accessible volume of 730 Å3. However, this procedure showed no electrons in the voids. This indicates that the crystal lost nearly all of its solvent of crystallization by the time it was used for data collection, without collapse of the structure.Data collection: APEX2 (Bruker, 2004); cell

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. |

Substituted pyrrolidine compounds possess antimicrobial and antifungal activity against various pathogens (Amalraj et al., 2003). Several optically active pyrrolidine compounds are used as intermediates in controlled asymmetric synthesis (Suzuki et al., 1994). The spiro-indole-pyrrolidine ring system is a frequently encountered structural motif in many biologically important and pharmacologically relevant alkaloids, e.g. vincrinstine, vinblastine and spirotypostatins (Cordell, 1981). Against this background and to ascertain the detailed information on its molecular conformation, the structure determination of the title compound has been carried out.
The pyrrolidine ring (N1—C5) adopts an envelope conformation, with puckering (Cremer & Pople, 1975) and asymmetry (Nardelli, 1983) parameters q2 = 0.416 (2) Å, ϕ = 137.5 (2)° and Δs(C5) = 2.8 (2)°. The indoline ring system is planar and the keto atom O3 lies on the plane. The sum of angles at atom N1 of the pyrrolidine ring (323.3°) is in accordance with sp3 hybridization (Beddoes et al., 1986). The ethoxycarbonyl group is in an extended conformation as evidenced by torsion angles C2—C6—O2—C7 of -170.3 (3)° and C6—O2—C7—C8 of 170.3 (3)°.
Intramolecular N1—H1···O1 and N1—H1···O3 hydrogen bonds generate S(5) and S(6) ring motifs (Bernstein et al. 1995), respectively. The crystal packing is stabilized by O—H···O, O—H···N, N—H···O and C—H···O hydrogen bonds, and C—H···π intermolecular interactions (Table 1) which link the molecules into a three-dimensional framework.
