Abstract top

In the title compound, C27H27NO5 (systematic name: 17-cyclopropylmethyl-14-hydroxy-6-oxo-4,5-epoxymorphinan-6-yl benzoate), which is the benzoate ester of the opioid receptor antagonist naltrexone, the dihedral angle between the two phenyl rings is 77.1 (1)°. In the crystal, a weak aromatic C-H...Ocarboxyl hydrogen bond involving the benzoate groups of adjacent molecules gives rise to a chain extending along the a-axis direction. The known absolute configuration for the molecule was inferred from a previous naltrexone structure.

Comment top

The title compound C27H27NO5 is the benzoate ester of the opioid receptor antagonist naltrexone and is important as an intermediate for the preparation N-methylnaltrexone bromide. It is used for the treatment of a number of diseases which are related to abnormal release of endogenous opium (Beznischenko et al., 2007). The structures of a number of derivatives of naltrexone are known, e.g. naltrexone hydrochloride dihydrate (Ledain et al., 1992) and methylnaltrexone hydrobromide methanol monosolvate (Li et al., 2012). In the title compound, the known absolute configuration for the molecule was inferred from a previous naltrexone structure (Li et al., 2012).

In the crystal, a weak aromatic C—H···Ocarboxyl hydrogen bond involving the benzoate moieties of adjacent molecules (Table 1) gives a one-dimensional chain extending along the a axial direction. Present also in the structure is an intramolecular O2—H···N interaction.

Experimental top

The title compound was prepared from 2.0 g (5.9 mmol) of naltrexone ([5α]-17-(cyclopropylmethyl-4,5-epoxy-3,14-dihydroxymorphinan-6-one)), 0.60 g of triethylamine and 16 ml of dichloromethane which were were successively introduced into a 100 ml reactor equipped with a condenser and a mechanical stirrer. After the solid had dissolved, benzoyl chloride (0.85 g, 6 mmol) was added over a 10 minute period at 20 °C and the reaction medium was refluxed for 2 h. The dichloromethane was removed under vacuum and the solid was recrystallized from ethanol, giving the pure title compound.

Refinement top

All H atoms attached to C atoms and N atom were fixed geometrically and treated as riding with C—H = 0.96 Å (methyl) or 0.97 Å (methylene) and N—H = 0.86 Å with Uiso(H) = 1.2Ueq(C or N) or Uiso(H) = 1.5Ueq(methyl). The hydroxy H-atom was located in a difference Fourier and included in the subsequent refinement using restraints [O—H = 0.85 (1) Å, with Uiso(H) = 1.5Ueq(O)]. The absolute structure [(C4R,C5S,C6S,C7R) for the current trivial atom numbering scheme] was inferred from a previous structure determination (Li et al., 2012) [Flack structure parameter (Flack, 1983) for the present compound = 0.04 (2) for 1886 Friedel pairs].

Special details top

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.
