Abstract
The title compound, C17H23NO4·H2O, is an epimer of the natural tetra-cyclic alkaloid isosaxorumamide which consists of a fused 5-7-5 tricyclic core and a di-hydro-furan-one substituent. The terminal di-hydro-furan ring is essentially planar with a maximum deviation of 0.0273 (14) Å from the mean plane and oxolane, azepane and pyrrolidine rings in the tricyclic ring system adopt twist, twist-chair and envelope forms, respectively. In the crystal, the amide and water mol-ecules are linked by O-H⋯O hydrogen bonds, forming a tape structure running along the b-axis direction. The tapes are further connected by C-H⋯O inter-actions into a three-dimensional architecture.
