Deskripsi
In the title compound, C26H37NO, a new derivative of dihydroabietic acid, the two cyclohexene rings adopt half chair conformations, whereas the cyclohexane ring has a chair conformation. Each of the methyl groups is in an axial position with respect to the tricyclic hydrophenanthrene residue. In the crystal packing, methylene-C—H...π(phenyl) interactions lead to supramolecular helical chains along [010]; the amide-H atom does not form a significant intermolecular interaction owing to steric pressure.
