O-Benzoyl-naltrexone.


ABSTRACT: In the title compound, C27H27NO5 (systematic name: 17-cyclopropylmethyl-14-hydroxy-6-oxo-4,5-epoxymorphin-an-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⋯Ocarbox-yl hydrogen bond involving the benzoate groups of adjacent mol-ecules gives rise to a chain extending along the a-axis direction. The known absolute configuration for the mol-ecule was inferred from a previous naltrexone structure.
