Abstract
In the title compound, C(16)H(17)N(3)O(4), the six-membered N-containing ring adopts a half-chair conformation. One C atom of the five-membered ring is disordered over two sites, with occupancy factors of ca 0.67 and 0.33. The major pyrroline component adopts a half-chair conformation. Inter-molecular C-H⋯O hydrogen bonds forming centrosymmetric dimers are observed in the crystal.
摘要
在标题化合物C(16)H(17)N(3)O(4)中，含氮六元环呈半椅式构象。五元环的一个碳原子在两个位置上无序，占有率分别约为0.67和0.33。主要的吡咯啉组分呈半椅式构象。在晶体中观察到分子间C-H⋯O氢键形成中心对称二聚体。
