In the isoquinoline ring system of the title compound, C(19)H(22)N(2)O(5), the N-heterocyclic ring is in a half-chair conformation. The dioxa-2-aza-spiro ring is essentially planar [maximum deviation of 0.025 (1) Å] and forms a dihedral angle of 23.51 (5)° with the benzene ring. In the crystal, mol-ecules are linked via weak inter-molecular C-H⋯O and C-H⋯N hydrogen bonds into chains along [010].
在标题化合物C(19)H(22)N(2)O(5)的异喹啉环系统中,N-杂环呈半椅式构象。二氧杂-2-氮杂螺环基本呈平面状[最大偏差为0.025 (1) Å],并与苯环形成23.51 (5)°的二面角。在晶体中,分子通过弱分子间C-H⋯O和C-H⋯N氢键沿[010]方向连接成链。
