Abstract

In the title compound, C₂₃H₂₂ClN₃O, the benzene ring of the 4-chorobenzyl group makes a dihedral angle of 78.56 (6)° with the best plane of the indole ring. The double bond connecting the azabicyclic and indole groups adopts a Z geometry. The geometry adopted by the C=N bond with respect to the N—OH bond is trans. The absolute configuration of the compound was determined from refinement of the Flack parameter.

Comment

In view of the radio-sensitization activity associated with N-benzylindolyl-1-azabicyclo[2.2.2]octan-3-ones (Sonar et al., 2007), we have undertaken the synthesis and structural analysis of a series of (2Z,3E)-2-((1-benzyl-1H-indol-3-yl)methylene) quinuclidin-3-one oximes. Systematic structural modification of the active molecule (Z)-2-(1-benzyl-1H-indol-3-ylmethylene)1- azabicyclo[2.2.2]octan-3-ol, was carried out, and the title compound was synthesized as its structural analogue. The X-ray analysis of the title compound was carried out to confirm the double-bond geometry of the molecule, and to determine the molecular conformation in the crystal structure.

X-ray crystallography confirmed the molecular structure and atom connectivity for title compound, as illustrated in Fig. 1. The indole ring is planar, with bond distances and angles comparable with those previously reported for other indole derivatives (Mason et al.., 2003; Zarza et al.., 1988). The benzene ring of the benzyl group linked to the N1 position of the indole ring is slightly twisted, making a dihedral angle of 78.56 (6)° with the plane of the indole ring system.

The title compound is the Z isomer, with the C10—C11 bond in a trans disposition with respect to the C8—C9 bond. The double bond has a nearly planar arrangement, since the r.m.s. deviation from the best plane passing through atoms N2/C10/ C11/C9/C8 is 0.0143 (15) Å. The azabicyclic system presents very small distortions around atoms N2, C14, C13, C12, C16 and C11. The value of the C1=C8—C9=C10 torsion angle -13.87° indicates the deviation of the indole ring from the plane of the double bond connected to the azabicyclic ring.

Experimental

Compound 2-((1-(4-chlorobenzyl)-1H-indol-3-yl)methylene) quinuclidin-3-one was prepared by aldol condensation of 1-(4-chlorobenzyl-indole-3-carboxaldehyde with 1-azabicyclo[2.2.2]octan- 3-one to afford (Z)-2-(1-(4-chlorobenzyl-1H-indol-3-yl methylene)-1-azabicyclo[2.2.2]octan-3-one, as a single geometric isomer, according to the previously reported procedure of Sonar et al. (2003). A mixture (Z)-2-(1-(4-chlorobenzyl-1H-indol-3-yl methylene)1-azabicyclo[2.2.2]octan-3-one (0.5 g, 1.32 mmol), hydroxylamine hydrocloride (0.18 g, 2.65 mmol) and sodium acetate trihydrate (0.36 g, 2.65 mmol) was stirred in methanol (25 ml) under reflux for 8 hrs. The reaction mixture was cooled to room temperature, diluted with water (15 ml), and the light yellow solid that separated was collected by filtration, washed with water and dried, to afford the the crude product. Crystallization from methanol gave a colorless crystalline product of (2Z,3E)-2- ((1-(4-chlorobenzyl)-1H-indol-3-yl)methylene) quinuclidin-3-one oxime that was suitable for X-ray analysis. ¹H NMR (CDCl₃): δ 1.76–1.79 (m, 4H), 2.91–3.09 (m, 4H), 3.67–3.69 (m, 1H), 5.34 (s, 2H), 7.01–7.04 (d, 2H), 7.10 (s, 1H), 7.14–7.25 (m, 5H), 7.30 (bs, 1H), 7.79–7.83 (d, 1H), 8.21 (s, 1H) p.p.m.; ¹³C NMR (DMSO d₆): δ 24.46, 25.87, 47.77, 50.06, 109.92, 110.45, 111.47, 119.34, 120.34, 122.39, 128.05, 128.63, 129.09, 131.27, 133.54, 135.80, 135.98, 138.23, 161.31 p.p.m..

Special details

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 > 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.
