چکیده
In the title compound, C35H27N3O3S, the spiro-linked five-membered rings both adopt twisted conformations. The pyrrolidine ring makes dihedral angles of 80.5 (1) and 77.4 (9)° with the benzo-thio-phene ring system and the quinoxaline ring system, respectively. The S atom and C=O unit of the benzo-thio-phene ring system are disordered over two opposite orientations in a 0.768 (4):0.232 (4) ratio. The atoms of the ethyl side chain are disordered over two sets of sites in a 0.680 (16):0.320 (16) ratio. In the crystal, mol-ecules are linked by C-H⋯O, C-H⋯N and π-π inter-actions [shortest centroid-centroid distance = 3.4145 (19) Å], resulting in a three-dimensional network.
