In the isoquinoline ring system of the title mol-ecule, C(16)H(16)N(2)O(5), the N-heterocyclic ring is in a half-boat conformation. The dioxaaza-spiro ring is essentially planar [maximum deviation = 0.022 (1) Å] and forms a dihedral angle of 24.56 (4)° with the benzene ring.
在标题分子C(16)H(16)N(2)O(5)的异喹啉环系统中,N-杂环呈半船式构象。二氧杂氮杂螺环基本呈平面状[最大偏差 = 0.022 (1) Å],并与苯环形成24.56 (4)°的二面角。
