The title compound, C21H21NO5, crystallizes with two mol-ecules in the asymmetric unit. In each mol-ecule, the central 1,4-di-hydro-pyridine ring adopts a shallow sofa conformations (with the C atom bearing the phenol ring as the flap), whereas the pendant cyclo-hexene rings both have twisted-boat conformations. Each mol-ecule features an intra-molecular O-H⋯O hydrogen bond, which closes an S(8) ring. In the crystal, the mol-ecules are linked by O-H⋯O, C-H⋯O and C-H⋯π inter-actions, forming a three-dimensional network.
标题化合物C21H21NO5在不对称单元中含有两个分子。在每个分子中，中心的1,4-二氢吡啶环呈浅沙发构象（以带有酚环的C原子为侧翼），而悬垂的环己烯环均呈扭船构象。每个分子都有一个分子内O—H⋯O氢键，形成一个S(8)环。在晶体中，分子通过O—H⋯O、C—H⋯O和C—H⋯π相互作用相连，形成三维网络。
