Abstract
The title compound, (1R,3S,4S,5S,6S,7R,8S)-8-(4-chlorophenyl)-3-hydroxy-7-methyl-6-nitro-N,5- diphenyl-2-oxabicyclo[2.2.2]octane-1-carboxamide-5, was synthesized and characterized by 1H, 13C NMR and HRMS spectroscopy. Its absolute molecular configuration was investigated by X-ray crystallography. Compound 5 co-crystallizes with methanol in the orthorhombic space group P 21 21 21 with cell parameters of a = 10.896(2) Å, b = 14.575(3) Å, c = 16.414(3) Å, V = 2606.7(9) Å3, and Z = 4. The crystal structure analysis revealed that the structure exhibits intermolecular hydrogen bonds of the types O-H…O, N-H…O, C-H…O.
