5-(4-Bromophenyl)-1,2,3,4-tetrahydrobenzo[a]phenanthridine

چکیده
The title compound, C(23)H(18)BrN, was synthesized by the reaction of 4-bromo-benzaldehyde, naphthalen-2-amine and cyclo-hexa-none in tetra-hydro-furan, catalyzed by iodine. The saturated six-membered ring adopts a half-chair conformation, and the four vicinal rings form a helical conformation, which results in a significant deviation from planarity for the pyridine ring. In the crystal, a weak C-H⋯π inter-action occurs, leading to inversion dimers.

In the mol-ecule of the title compound, C(20)H(13)BrN(2)O, the tetra-hydro-benzo[h]quinoline fused-ring system is buckled owing to the ethyl-ene -CH(2)CH(2)- fragment, the benzene ring and the pyridine ring being twisted by 17.7 (1)°. The 4-substituted aromatic ring is bent away from the pyridine ring by 82.3 (1)° in order to avoid crowding the cyanide substituent. Two mol-ecules are linked by ...
