The title compound, C36H31N2O3+,C2H3O2−·2C2H5OH, the product of a domino condensation of dibenzyl ketone with salicylic aldehyde and ammonium acetate, crystallized as the ethanol disolvate. The cation of the salt comprises a fused tricyclic system containing three six-membered rings (piperidine, dihydro-2H-pyran and benzene). The piperidine ring has the usual chair conformation, while the dihydropyran ring adopts a slightly distorted sofa conformation. In the crystal, there are six (one intra- and five intermolecular) independent hydrogen-bonding interactions: the intermolecular hydrogen bonds link the cations and anions and ethanol solvent molecules into ribbons along [001]. The ribbons are stacked along the a axis.

Ammonium acetate (4.0 g, 52 mmol) was added to a solution of dibenzyl ketone (2.1 g, 10 mmol) and salicylic aldehyde (3.66 g, 30 mmol) in ethanol (50 ml) (Fig. 3). The reaction mixture was stirred for 96 h at 293 K (monitoring by TLC until disappearance of the starting ketone spot). At the end of the reaction, the formed precipitate was filtered off, one half of the mother liquid solvent removed under reduced pressure and the residue was cooled to give 1.45 g of light-yellow crystals of I. Yield is 21%. M.p. = 451–453 K.

The hydrogen atoms of the hydroxy and amino groups were localized in the difference Fourier map and included in the
with fixed positional and isotropic displacement parameters [Uiso(H) = 1.5Ueq(O) and 1.2Ueq(N)]. The other hydrogen atoms were placed in calculated positions with C—H = 0.95–1.00Å and refined in the riding model with fixed isotropic displacement parameters [Uiso(H) = 1.5Ueq(C) for CH3-groups and Uiso(H) = 1.2Ueq(C) for the other groups].Data collection: APEX2 (Bruker, 2005); cell

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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. |

Recently our group has found an efficient method of the one-step synthesis of potentially bioactive substances having oxazocine skeletal structure. These molecules are formed by domino condensation from commercially available dibenzyl ketone, salicylic aldehyde and ammonium acetate as starting materials (Soldatenkov et al., 2010). The key step of this condensation is Petrenko–Kritchenko reaction (Baliah et al., 1983) leading to the formation of the substituted γ-piperidone (Le Tuan Anh et al., 2008), which then reacts with the excess of ammonium acetate and aldehyde. This work reports the structural characterization of a product of such reaction - 2-oxa-6-aza-3,4-benzobicyclo[3.3.11,5]nonan-6-ium acetate (I).
Compound I crystallizes as diethanol solvate, i.e., C38H34N2O5.2(C2H6O). The cation of the salt I comprises a fused tricyclic system containing three six-membered rings (piperidine, dihydro-2H-pyran and benzene) (Fig. 1). The piperidine ring has the usual chair conformation, while the dihydropyran ring adopts the slightly distorted sofa conformation (the C13 carbon atom deviates from the plane passed through the other atoms of the ring by 0.691 (2) Å). The phenyl substituents at the C10 and C11 carbon atoms occupy the sterically favorable equatorial positions, whereas the phenyl substituent at the C13 carbon atom is axially disposed.
The cation of I possesses four asymmetric centers at the C1, C10, C11, and C13 carbon atoms and can have potentially numerous diastereomers. The crystal of I is racemic and consists of enantiomeric pairs with the following relative configuration of the centers: rac-1S*,10R*,11S*, 13S*.
In the crystal, there are six (one intra- and five intermolecular) independent hydrogen bonding interactions (Table 1). The intermolecular hydrogen bonds link the cations and anions of I and ethanol solvate molecules into ribbons along the direction [0 0 1] (Fig. 2). The crystal packing of the ribbons is stacked along the a axis.
