9-(4-Hy­droxy-3-meth­oxy­phen­yl)-3,3,6,6-tetra­methyl-1,2,3,4,5,6,7,8,9,10-deca­hydro­acridine-1,8-dione

In the title mol­ecule, C₂₄H₂₉NO₄, the central ring of the acridinedione system adopts a flat boat conformation and the four essentially planar atoms of this ring [maximum deviation = 0.001 (2) Å] form a dihedral angle of 85.99 (12)° with the benzene ring. The two outer rings of the acridinedione system adopt sofa conformations. In the crystal, O—H...O and N—H...O hydrogen bonds link the mol­ecules, forming a two-dimensional network parallel to (100).

9-(3-Fluoro­phen­yl)-3,3,6,6-tetra­methyl-1,2,3,4,5,6,7,8,9,10-deca­hydro­acridine-1,8-dione

In the title mol­ecule, C₂₃H₂₆FNO₂, the central ring of the acridinedione system adopts a slight boat conformation and the four essentially planar atoms of this ring [maximum deviation = 0.019 (1) Å] form a dihedral angle of 89.98 (6)° with the benzene ring. The two outer rings of the acridinedione system adopt sofa conformations. In the crystal, N—H...O hydrogen bonds link the mol­ecules, forming chains along [001].

2-Amino-7,7-dimethyl-5-oxo-4-[3-(trifluoro­meth­yl)phen­yl]-1,4,5,6,7,8-hexa­hydro­quinoline-3-carbonitrile

In the title mol­ecule, C₁₉H₁₈F₃N₃O, the dihydro­pyridine and cyclo­hexene rings both adopt sofa conformations. The five essentially planar atoms of the dihydro­pyridine ring [maximum deviation = 0.039 (2) Å] form a dihedral angle of 88.19 (8)° with the benzene ring. The F atoms of the trifluoro­methyl group were refined as disordered over two sets of sites in a 0.840 (3):0.160 (3) ratio. In the crystal, N—H...O and N—H...N hydrogen bonds link mol­ecules into a two-dimensional network parallel to (100).
