Abstract: The asymmetric unit of the title compound, C44H44N2O6, contains two independent mol­ecules with similar conformations. The di­hydro­naphthalene ring systems are approximately planar [maximum deviations = 0.036 (2), 0.128 (2), 0.0.24 (2) and 0.075 (2) Å]. The dihedral angle between two di­hydro­naphthalene ring systems is 83.37 (4)° in one mol­ecule and 88.99 (4)° in the other. The carbonyl O atom is linked with the adjacent hy­droxy and imino groups via intra­molecular O-H...O and N-H...O hydrogen bonds. In the crystal, mol­ecules are linked through O-H...O hydrogen bonds into layers parallel to (001), and adjacent layers are further stacked by [pi]-[pi] inter­actions between di­hydro­naphthalene and phenyl rings into a three-dimensional supra­molecular architecture. In the crystal, one of the isopropyl groups is disordered over two positions with an occupancy ratio of 0.684 (8):0.316 (8).
