2,2′-[(4-Eth­oxy­phen­yl)methyl­ene]bis­(3-hy­droxy-5,5-dimethyl­cyclo­hex-2-en-1-one)

In the title compound, C₂₅H₃₂O₅, the two cyclo­hexenone rings have envelope conformations with the C atom bearing two methyl groups as the flap atom in each ring. Relatively strong intra­molecular O—H...O hydrogen bonds are observed.

10-Benzyl-9-(4-eth­oxy­phen­yl)-3,3,6,6-tetra­methyl-3,4,6,7,9,10-hexa­hydro­acridine-1,8(2H,5H)-dione

In the title compound, C₃₂H₃₇NO₃, the central dihydro­pyridine ring adopts a nearly planar flattened-boat conformation, whereas both cyclo­hexenone rings adopt half-chair conformations. The mean and maximum deviations from the mean plane of the dihydro­pyridine ring are 0.1252 (9) and 0.188 (1) Å, respectively. The 4-eth­oxy­phenyl and phenyl rings form dihedral angles of 75.20 (4) and 82.14 (5)° with the dihydro­pyridine mean plane, respectively.
