In the title isatin compound, C(16)H(18)N(2)O(6), the pyrrolidine ring adopts an envelope conformation and is inclined at a dihedral angle of 7.31 (5)° with respect to the benzene ring. The acetyl group is disordered over two positions with refined occupancies of 0.503 (4) and 0.497 (4). These groups make dihedral angles of 12.6 (6) and 19.6 (7)° with the pyrrolidine ring. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link neighbouring mol-ecules into infinite chains along the b axis. These chains are further inter-connected by inter-molecular O-H⋯O hydrogen bonds into two-dimensional arrays parallel to the bc plane. Weak inter-molecular C-H⋯π inter-actions further stabilize the crystal structure.
在标题异吲哚酮化合物C(16)H(18)N(2)O(6)中，吡咯烷环呈信封构象，相对于苯环的二面角为7.31 (5)°。乙酰基在两个位置上无序，精制占有率分别为0.503 (4)和0.497 (4)。这些基团与吡咯烷环的二面角分别为12.6 (6)°和19.6 (7)°。在晶体结构中，分子间的C—H⋯O氢键将相邻分子沿b轴连接成无限链。这些链通过分子间的O—H⋯O氢键进一步相互连接成平行于bc平面的二维阵列。弱的分子间C—H⋯π相互作用进一步稳定了晶体结构。
