2662por Dardouri, Rachida, Rodi, Youssef Kandri, Ladeira, Sonia, Essassi, El Mokhtar, Ng, Seik Weng“…The seven-membered ring of the title compound, C(18)H(16)N(2)O(3), adopts a boat-shaped conformation (with the C atoms of the fused ring as the stern and the methine C atom as the prow). The substituent at the 3-position occupies an axial position, and the aromatic ring of the substituent is arched over the seven-membered ring in a parasol-like manner, the dihedral angle between the phenylene and phenyl rings being 28.7 (1)°.…”
