The relative stereochemistry of the title compound, C(20)H(23)NO(3), was established by X-ray analysis. The asymmetric unit contains two independent mol-ecules. In the crystal structure, each type of mol-ecule forms a centrosymmetric dimer via pairs of inter-molecular O-H⋯O hydrogen bonds, resulting in an R(2) (2)(10) loop in each case.
标题化合物C(20)H(23)NO(3)的相对立体化学通过X射线分析得以确定。不对称单元包含两个独立分子。在晶体结构中,每种类型的分子通过分子间O-H⋯O氢键对形成中心对称二聚体,每种情况下均产生一个R(2) (2)(10)环。
