Abstract: The title compound, the product of an acid-catalysed Wagner-Meerwein skeletal rearrangement, crystallizes as an ethanol monosolvate, C₂₀H₂₁NO₈·C₂H₆O. The title molecule comprises a fused tricyclic system containing two five-membered rings (cyclopentane and tetrahydrofuran) in the usual envelope conformations and one six-membered ring (piperidinone) adopting a flattened twist-boat conformation.
