Abstract: The title compound, C39H39N3O4, although having potential C2 molecular symmetry, crystallizes as an asymmetric conformer, due to a couple of strong intramolecular hydrogen bonds involving hydroxyl groups and a pyridine N atom. This geometrical feature explains why this compound behaves as a poor chiral inductor for asymmetric synthesis.
