The asymmetric unit of the title compound, C44H44N2O6, contains two independent mol-ecules with similar conformations. The di-hydro-naphthalene 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 di-hydro-naphthalene ring systems is 83.37 (4)° in one mol-ecule and 88.99 (4)° in the other. The carbonyl O atom is linked with the adjacent hy-droxy and imino groups via intra-molecular O-H⋯O and N-H⋯O hydrogen bonds. In the crystal, mol-ecules are linked through O-H⋯O hydrogen bonds into layers parallel to (001), and adjacent layers are further stacked by π-π inter-actions between di-hydro-naphthalene and phenyl rings into a three-dimensional supra-molecular 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).
