N-Benzylidenenordehydroabietylamine
Abstract
The title compound [systematic name: (1R,4aS,10aR,E)-N-benzylidene-7-isopropyl-1,4a-dimethyl-1,2,3,4,4a,9,10,10a-octahydrophenanthren-1-amine], C26H33N, has been synthesized from nor-dehydroabietylamine and benzaldehyde. The two cyclohexane rings form a trans ring junction with classic chair and half-chair conformations, respectively, the two methyl groups are on the same side of tricyclic hydrophenanthrene structure. The dihedral angle between two benzene rings is 44.2 (4)°. The C=N bond is in an E configuration.
