3-Ethyl-2-phenyl­sulfonyl-1,2,3,3a,10,10a,11,11a-octa­hydro-5H-pyrrolo[3,4:2′,3′]pyrrolo[1,5-b]isoquinolin-5-one

In the title mol­ecule, C22H24N2O3S, the fused pyridinone ring adopts a half-chair conformation while the pyrrolidine rings adopt envelope and twist conformations. C—H⋯O inter­actions link the mol­ecules into a three-dimensional network.
