There are two mol-ecules in the asymmetric unit of the title compound, C(26)H(24)ClNO(3). The dihedral angles between the naphthalene ring system and the chloro-phenyl substituent are 58.76 (9) and 51.59 (8)° in the two mol-ecules. In the pyrrolizine ring system, both the pyrrolidine rings adopt envelope conformations and the dihydro-pyran rings adopt half-chair conformations. In the pyrrolizine ring system of one of the mol-ecules, one of the C atoms is disordered over two positions with site occupancies of 0.69 (2) and 0.31 (2). The crystal packing is stabilized by weak intra-molecular C-H⋯O inter-actions and the crystal packing is stabilized by weak C-H⋯π inter-actions.
标题化合物C(26)H(24)ClNO(3)的不对称单元中有两个分子。在这两个分子中，萘环系统与氯苯基取代基之间的二面角分别为58.76 (9)°和51.59 (8)°。在吡咯嗪环系统中，两个吡咯烷环均呈信封式构象，二氢吡喃环呈半椅式构象。在其中一个分子的吡咯嗪环系统中，一个C原子在两个位置上无序，占位分别为0.69 (2)和0.31 (2)。晶体堆积通过弱分子内C-H⋯O相互作用得以稳定，且通过弱C-H⋯π相互作用得以稳定。
