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

Abstract: In the title compound, C₂₆H₃₀N₂O₄S·H₂O, 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-HO hydrogen bonds involving water molecules and C-H interactions involving the sulfonyl-bound phenyl ring. Adjacent ribbons are cross-linked via C-HO hydrogen bonds involving a sulfonyl O atom and C-H interactions involving the pyridinone ring.
