Abstract

In the title compound, C(25)H(25)NO(3), the dihydro-pyran ring adopts a half-chair conformation, whereas the pyrrolidine ring is in a twist conformation. The tolyl group is oriented at an angle of 82.92 (7)° with respect to the napthalene ring system. In the crystal structure, mol-ecules are linked into centrosymmetric dimers by C-H⋯π inter-actions involving the benzene ring of the tolyl group.

摘要

在标题化合物C₂₅H₂₅NO₃中，二氢吡喃环呈半椅式构象，而吡咯烷环处于扭曲构象。甲苯基相对于萘环系统的取向角度为82.92 (7)°。在晶体结构中，分子通过涉及甲苯基苯环的C-H⋯π相互作用连接成中心对称二聚体。
