description | The title compound, C17H24O5, featuring a 2-carbethoxy-3-oxepanone unit in its intramolecularly O—H...O hydrogen-bonded enol form, was obtained via [(CF3CO2)2Rh]2-catalysed intramolecular O—H bond insertion in the α-diazo-ω-hydroxy-β-ketoester, ethyl 4-[(1S,3aS,6R,6aS)-6-hydroxy-2,2,3a-trimethyl-3-oxo-octahydropentalen-1-yl]-2-diazo-3-oxobutanoate. The seven-membered oxacyclic ring, thus constructed on a cis-fused diquinane platform, was found to adopt a distorted boat–sofa conformation. |
