7-Methyl-9-p-tolyl-4,9-dihydrofuro[3,4-b]quinolin-1(3H)-one
In the title compound, C(19)H(17)NO(2), the dihydro-pyridine ring adopts a flattened boat conformation while the furan-one ring is almost planar (r.m.s. deviation 0.018 Å). The mol-ecules are linked into chains along the b axis by N-H⋯O inter-molecular hydrogen bonds. In addition, C-H⋯π inter-actions involving the phenyl ring of the tolyl group as π acceptor are observed.

The title compound, C(26)H(19)ClN(2), is a 5,6-dihydro-13H-indolo[3,2-c]acridine prepared by condensation of a 2,3,4,9-tetra-hydro-1H-carbazol-1-one with 2-amino-benzophenone. The crystals undergo a destructive phase change upon cooling at varying temperatures between 270 and 200 K, depending on cooling rate and disturbance by vibration, thus indicating supercooling of the metastable room-tempe...

In the title mol-ecule, C(19)H(15)F(3)N(2)O, the benzene rings of the tolyl and trifluoro-methyl-phenyl groups form dihedral angles of 64.1 (2) and 38.5 (2)°, respectively, with the pyridazine ring. The CF(3) group is disordered over two orientations, with site-occupancy factors of ca 0.56 and 0.44.

In the title compound, C(22)H(17)NO(2), the fused ring system is essentially planar (r.m.s. deviation = 0.021 Å) and the dihedral angle between the dihydro-pyridine and tolyl rings is 80.98 (11)°. In the crystal, the mol-ecules are linked into chains along the b axis by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds. Adjacent chains are linked by π-π inter-actions [centroid-centroid separation ...
