Abstract top

The title compound (systematic name: 16-hydroxymethyl-12-methoxyibogamine), C21H28N2O2, was prepared by reaction of ibogaine with a formaldehyde-acetic acid solution (pH = 4). The crystal structure of this new product, belonging to the iboga indole family, is stabilized by an intermolecular O-H...N hydrogen bond. The identity of the compound was confirmed by one- and two-dimensional NMR spectroscopic techniques.

Comment top

Ibogaine is the main alkaloid found in the root bark of Tabernanthe iboga (Apocynaceae family), a shrub native to equatorial Africa. Its crystal structure was previously established by M. Soriano-García (1992). It is used, at low doses, to produce increased energy, arousal, and appetite and at high doses, for its hallucinogenic properties (Maisonneuve et al., 1991) and it has been claimed to be effective in abolishing drug craving in heroin and cocaine addicts (Levant & Pazdernik, 2004).

Ibogaine is a psychostimulant of interest as an ethnopharmacological prototype for experimental investigation and possible rational pharmaceutical development (Alper et al., 2008). In this context and in order to prepare other substitutes, we realised the reaction of ibogaine with a formaldehyde-acetic acid solution (pH= 4). This reaction led to 47% of the title compound (Fig. 1).

The current study describes the preparation and the structure elucidation of N-hydroxymethylene ibogaine. Its structure was established principally by two-dimensional NMR spectroscopy and its solid state structure was determined through X-ray diffraction analysis (Fig. 2, Fig. 4).

The conformation of this compound is stabilized by an intermolecular hydrogen bond between the hydroxyl O2—H2 group and atom N4 (Fig. 3).

Experimental top

The title compound (2) was prepared by reaction of ibogaine (1) (100 mg, 0.3 mmol) with formaldehyde-acetic acid solution (pH= 4) (10 ml). The mixture was stirred at room temperature for 2 h. Then, the mixture was diluted with H2O, made alkaline with an NH4OH solution (pH = 9) and immediately extracted with CH2Cl2. The organic phase was dried over sodium sulfate, filtered and concentrated under reduced pressure. The concentrate was then purified by chromatography on silica gel column with dichloromethane as eluent to yield 47% of the title compound.

Repeated recrystallizations from dichloromethane afforded white crystals suitable for single crystal X-ray diffraction.

Refinement top

All H atoms were fixed geometrically and treated as riding with C—H = 0.98 Å (Cmethine), 0.97 Å (Cmethylene), 0.96 Å (Cmethyl), 0.93 Å (CH2) and O—H = 0.82 Å with Uiso(H) = 1.2Ueq(Cmethylene, methine, CH2) or Uiso(H) = 1.5Ueq(Cmethyl, O).

In the absence of anomalous scattering Friedel pairs were merged and any references to the Flack parameter were removed.

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All esds are estimated from the variances of the (full) variance-covariance matrix. The cell esds are taken into account in the estimation of distances, angles and torsion angles

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.
