The title compound, C18H22N2O5, was synthesized by of its enol precursor. The pyrrolidine ring plane adopts a twisted conformation about the C—C bond linking the spiro centre and the C=O group remote from the N atom. It makes dihedral angles of 71.69 (9) and 88.92 (9)°, respectively, with the benzene ring plane and the plane defined by the four C atoms that form the seat of the of the cyclohexane chair. At the spiro centre, the NH group is axial and the C=O group is equatorial with respect to the cyclohexane ring. In the crystal, inversion dimers linked by pairs of N—H⋯O hydrogen bonds generate R22(8) loops. The dimers are linked by C—H⋯O interactions, generating a three-dimensional network.

A solution of fuming nitric acid (0.92 g, 16mmoL) in anhydrous chloroform (10 ml) was added dropwise to a solution of compound 2 (1.78 g, 5.9mmoL) in anhydrous chloroform (20 ml) at 0 degree and stirred for 2 h. The reaction mixture was then washed with ice water (15 ml), and saturated sodium chloride solution and dried over anhydrous Na2SO4. The solvent was evaporated, and the residual solid was crystallized from ethanol to afford 1.84 g compound 3 as a pale yellow solid: yield 90%.

Spirotetramat is a new systemic insecticide which chemically belongs to the class of spirocyclic tetramic acid derivatives and be developed by Bayer CropScience AG (Fischer et al., 2008; Maus, 2008). A unique mode of action coupled with a high degree of activity on targeted pests and low toxicity to nontarget organisms make spirocyclic tetronic acid compounds as a new tool for integrated pest management (Bruck et al., 2009; Campbell et al.,1985; Schobert et al., 2008) In order to study the influence of new substituents on the activity of the Spirotetramat derivative, the title compound, has been synthesized and its structure has been determined (Fig. 1). The molecule contains one benzene ring, one six membered ring, and one five membered ring. The cyclohexane ring adopts a chair conformation;the C13, C14, C16 and C17 atoms are on one plane with C15 and C11 deviating by 0.658 (5)and -0.676 (9) Å, respectively. There are three planes in the molecule: atoms of C10, C11, C12 and N2 generate the pyrrolidine plane (I), C1—C6 yield the benzene plane (II) and C13—C14 and C16—C17 form the cyclohexane plane(III). The angle between planes I and II is 71.69 (9) °, and that between planes I and III is 88.92 (9) °. The space arrangement might result from the space factor between groups.

Experimental. Absorption correction: CrysAlisPro, Agilent Technologies, Version 1.171.35.11 (release 16-05-2011 CrysAlis171 .NET) (compiled May 16 2011,17:55:39) Empirical absorption correction using spherical harmonics, implemented in SCALE3 ABSPACK scaling algorithm. |
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. |

Spirotetramat is a new systemic insecticide which chemically belongs to the class of spirocyclic tetramic acid derivatives and be developed by Bayer CropScience AG (Fischer et al., 2008; Maus, 2008). A unique mode of action coupled with a high degree of activity on targeted pests and low toxicity to nontarget organisms make spirocyclic tetronic acid compounds as a new tool for integrated pest management (Bruck et al., 2009; Campbell et al.,1985; Schobert et al., 2008) In order to study the influence of new substituents on the activity of the Spirotetramat derivative, the title compound, has been synthesized and its structure has been determined (Fig. 1). The molecule contains one benzene ring, one six membered ring, and one five membered ring. The cyclohexane ring adopts a chair conformation;the C13, C14, C16 and C17 atoms are on one plane with C15 and C11 deviating by 0.658 (5)and -0.676 (9) Å, respectively. There are three planes in the molecule: atoms of C10, C11, C12 and N2 generate the pyrrolidine plane (I), C1—C6 yield the benzene plane (II) and C13—C14 and C16—C17 form the cyclohexane plane(III). The angle between planes I and II is 71.69 (9) °, and that between planes I and III is 88.92 (9) °. The space arrangement might result from the space factor between groups.
