The title compound, C30H34N2O9 (4), is a product of the Michael reaction of azacrown ether with dimethyl acetylenedicarboxylate modified by an addition of NH3 (aq.) at 298 K. The aza-14-crown-4-ether ring adopts a bowl conformation. The dihedral angle between the planes of the benzene rings fused to the aza-14-crown-4-ether moiety is 8.65 (5)°. The tetrahydropyridine ring has a boat conformation. The molecular conformation is supported by one N—H⋯O and two C—H⋯O intramolecular hydrogen bonds. Both heterocyclic and amino N atoms have essentially planar configurations (sums of the bond angles are 359.35 and 358.00°). Compound 4 crystallizes as a racemate consisting of enantiomeric pairs of the 1R,21S diastereomer. In the crystal, molecules of 4 are connected by N—H⋯O hydrogen bonds, forming chains along [100]. According to the PASS program (computer prediction of biological activities), compound 4 may exhibit antiallergic (72% probability) and antiasthmatic (67%) activity, as well as be a membrane permeability inhibitor (65%).

1. Chemical context
Over the last several decades, azacrown ; Pedersen, 1988; Schwan & Warkentin, 1988; Gokel & Murillo, 1996; Bradshaw & Izatt, 1997). Recently, we have developed effective new methods for the synthesis of azacrown containing the heterocyclic subunits piperidine (Levov et al., 2006, 2008a, b; Anh et al., 2008, 2012a,b,c; Hieu et al. 2012a,b, 2013a), perhydropyrimidine (Hieu et al., 2011), perhydrotriazine (Khieu et al., 2011), pyridine (Le et al., 2014; Tuan et al., 2015; Anh et al., 2018) and bispyridine (Komarova et al., 2008; Sokol et al., 2011). These new azacrown compounds also are interesting as potential anticancer agents because of their cytotoxicity (Le et al., 2014; Le et al., 2015; Ahn et al., 2018).
have been designed, synthesized and applied as macrocyclic ligands for coordination chemistry (Hiraoka, 1978In our previous work, we have studied the Michael addition of azacrown et al., 2012a,b; Hieu et al. 2013a,b). We have also found recently that the expected N-vynilation proceeded smoothly with the formation of an N-maleinate derivative of the azacrown system. Modification of the reaction by the addition of NH3 (aq.) and continuous stirring for three days at 298 K produced the unexpected γ-amino-N-propylpiperidine (4) in a yield of 40% (Fig. 1). According to the PASS program (Prediction of Activity Spectra for Substances – i.e. computer prediction of biological activities; Sadym et al., 2003), the title compound has the potential to exhibit antiallergic (72% probability), antiasthmatic (67%) and membrane permeability inhibiting (65%) activities. The obtained compound was studied by X-ray (Fig. 2).

The molecule of 4, C30H34N2O9, comprises a fused tetracyclic system containing the aza-14-crown-3-ether macrocycle, one piperidine and two benzene rings (Fig. 2). The aza-14-crown-3-ether ring adopts a bowl conformation. The configuration of the C7—O8—C9—C10 —O11—C12—C13—O14—C15 polyether chain is t—g(−)—g(−)—t—g(+)—t (t = trans, 180°; g = gauche, ±60°). The dihedral angle between the planes of the benzene rings fused to the aza-14-crown-4-ether moiety is 8.65 (5)°. The tetrahydropyridine ring adopts a boat conformation. The conformations of the aza-14-crown-4-ether and piperidine rings are supported by the three intramolecular (one N—H⋯O and two C—H⋯O) hydrogen bonds (Table 1). The nitrogen N23 and N25 atoms have practically planar geometries (the sums of the bond angles are 359.35 and 358.00°, respectively).
The molecule of 4 possesses two asymmetric centers at the C1 and C21 carbon atoms and potentially can have four The crystal of 4 is racemic and consists of enantiomeric pairs with the following of the centers: 1R,21S.
3. Supramolecular features
In the crystal, molecules of 4 form hydrogen-bonded chains propagating along [100] through strong intermolecular N—H⋯O hydrogen bonds (Fig. 3, Table 1). The chains are stacking along the b-axis direction.
4. Synthesis and crystallization
A solution of 1.30 g (10.00 mmol) of ethyl acetoacetate (1), 3.14 g (10.00 mmol) of 1,5-bis-(2-formylphenoxy)-3-oxaopetane (2) and 1.00 g (13.00 mmol) of ammonium acetate in a mixture of 30 ml ethanol and 1 ml acetic acid was stirred at 298 K. The reaction was monitored by TLC and found to be complete after 6 h. The reaction mixture was allowed to cool to room temperature before being neutralized with sodium carbonate solution; the product was then extracted with chloroform (3 × 50 ml). By TCL, compound 3 was determined to be successfully synthesized. The solvent (CDCl3) was evaporated under vacuum until 30ml of CDCl3 was left, 1.42 g (10 mmol) of DMAD was added and the solution was stirred for 30 minutes at 298 K. Then NH3 (aq.) was added to the reaction mixture, which was stirred continuously. After three days, the residue was purified by and recrystallized from ethanol to obtain 2.27 g of the pure azacrown ether 4 as light-yellow crystals (yield 60%). Tm = 525–526 K. Rf = 0.85 [n-hexane:ethyl acetate = 1:1 (v:v)].
5. Refinement
Crystal data, data collection and structure . The hydrogen atoms of the amino group were localized in difference-Fourier maps and refined isotropically with constrained thermal displacement parameters [Uiso(H = 1.2Ueq(N)]. Other hydrogen atoms were placed in calculated positions with C—H bond lengths of 0.95–1.00 Å and refined using a riding model with constrained isotropic displacement parameters [Uiso(H) = 1.5Ueq(C) for the CH3 groups and 1.2Ueq(C) for all others].

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