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

ABSTRACT: In the title compound, C(26)H(30)N(2)O(4)S·H(2)O, the pyrrolidine and dihydro-pyran rings adopt envelope conformations and they are cis-fused. The sulfonyl group has a distorted tetra-hedral geometry. In the crystal structure, the mol-ecules are linked into a ribbon-like structure along the a axis by O/C-H?O hydrogen bonds involving water mol-ecules and C-H?? inter-actions 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?? inter-actions involving the pyridinone ring.
