The title compound, C17 H23 NO4 ·H2 O, is an epimer of the natural tetracyclic alkaloid isosaxorumamide which consists of a fused 5-7-5 tricyclic core and a dihydrofuranone substituent. The terminal dihydrofuran 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 molecules 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 interactions into a three-dimensional architecture.
