标题化合物的绝对构型已由X-射线衍射分析确定。晶体为正交晶系，空间群为P212121，晶胞尺寸为：a= 12.319（10），B= 27.170（26），c= 6.294（5）nm，Z= 4。在衍射仪上收集强度数据，并通过标准方法解析结构，并针对616个观察到的反射将其精修至R 0.070。苄型α-碳原子的绝对构型为（S），讨论了分子的构象。
The absolute configuration of the title compound has been determined by X-ray diffraction analysis. Crystals are orthorhombic, space group P212121, with Z= 4 in a unit cell of dimensions: a= 12.319(10), b= 27.170(26), c= 6.294(5)Å. Intensity data were collected on a diffractometer and the structure solved by standard methods and refined to R 0.070 for 616 observed reflections. The absolute configuration about the benzylic α-carbon atom is (S); the conformation of the molecule is discussed.
