1-Ethyl-2-tosyl-4,4,6-trimethyl-2,3,3a,4-tetra­hydro-1H-pyrrolo[3,4-c]pyrano[6,5-b]quinoline-11(6H)-one monohydrate

In the title compound, C(26)H(30)N(2)O(4)S·H(2)O, the pyrrolidine and dihydro­pyran rings adopt envelope conformations and they are cis-fused. The sulfonyl group has a distorted tetra­hedral geometry. In the crystal structure, the mol­ecules are linked into a ribbon-like structure along the a axis by O/C—H⋯O hydrogen bonds involving water mol­ecules and C—H⋯π inter­actions involving the sulfonyl-bound phenyl ring. Adjacent ribbons are cross-linked via C—H⋯O hydrogen bonds involving a sulfonyl O atom and C—H⋯π inter­actions involving the pyridinone ring.
