The β-lactam (azetidin-2-one) ring of the title compound, C28H27N3O5, is nearly planar [maximum deviation = 0.010 (1) Å] and makes dihedral angles of 75.77 (5), 52.78 (9) and 88.72 (5)°, respectively, with the benzene ring, the least-squares plane formed by the four C atoms of the morpholine ring, which adopts a chair conformation, and the xanthene ring system. In the crystal, C-H⋯O hydrogen-bond contacts connect neighbouring mol-ecules into infinite zigzag chains running parallel to the b axis.
标题化合物C28H27N3O5的β-内酰胺（氮杂环丁烷-2-酮）环近乎平面[最大偏差 = 0.010 (1) Å]，分别与苯环、由呈椅式构象的吗啉环的四个C原子形成的最小二乘平面以及呫吨环系统形成的二面角为75.77 (5)°、52.78 (9)°和88.72 (5)°。在晶体中，C—H⋯O氢键接触将相邻分子连接成平行于b轴的无限之字形链。
