Ethyl 6-(6-meth-oxy-naphthalen-2-yl)-4-(naphthalen-2-yl)-2-oxocyclo-hex-3-ene-1-carboxyl-ate.

The title compound, C30H26O4, contains an oxo-cyclo-hexane ring in a distorted half-chair configuration, with disorder of two C atoms in a 0.859 (4):0.141 (4) ratio.

(E)-1-(4-Methyl-phen-yl)ethanone [8-(trifluoro-meth-yl)quinolin-4-yl]hydrazone.

In the title compound, C(19)H(16)F(3)N(3), the dihedral angle between the naphthalene and quinoline ring systems is 14.58 (8)°. The hydrazone C-N-N=C-C chain is in an extended conformation and its mean plane is nearly coplanar with the quinoline plane [dihedral angle = 3.

2-(4-Methoxy-phen-yl)-6-trifluoro-methyl-1H-pyrrolo[3,2-c]quinoline monohydrate.

In the title compound, C(19)H(13)F(3)N(2)O·H(2)O, the phenyl and pyrroloquinoline ring system are close to coplanar [dihedral angle = 10.94 (4)°]. The meth-oxy group also is almost coplanar with the phenyl ring [5.

Ethyl 6-(6-meth-oxy-2-naphth-yl)-2-oxo-4-(2-thien-yl)cyclo-hex-3-ene-1-carboxyl-ate.

The title compound, C(24)H(22)O(4)S, was prepared by reaction between (2E)-3-(6-meth-oxy-2-naphth-yl)-1-(2-thien-yl)prop-2-en-1-one and ethyl acetoacetate. In the crystal, the cyclo-hexenone ring shows a distorted half-chair conformation. The length of the double bond in the cyclohexenone ring [1.
