title: N-(2-Pyridylmethyleneamino)dehydro-abietylamine.
abstract: The title compound {systematic name: 1-[(1R,4aS,10aR)-7-isopropyl-1,2,3,4,4a,9,10,10a-octa-hydro-phenanthren-1-yl]-N-[(E)-2-pyridylmethyleneamino]methanamine}, C(26)H(33)N(2), has been synthesized from dehydro-abietylamine. The two cyclo-hexane rings form a trans ring junction with classic chair and half-chair conformations, respectively, whereas the benzene and pyridine rings are almost planar, and the dihedral angle between them is 80.4°. The two methyl groups directly attached to the tricyclic nucleus are on the same side of the tricyclic hydro-phenanthrene structure.
