title: (±)-syn-Isopropyl 4-(1,1,1,3,3,3-hexa-fluoro-propan-2-yl-oxy)-1-hydr-oxy-3-methyl-2-(prop-1-yn-yl)cyclo-pent-2-ene-carboxyl-ate.
abstract: The title compound, C(16)H(18)F(6)O(4), was obtained through an unprecedented one-pot reaction sequence involving a Gosteli-Claisen rearrangement and a cyclo-isomerization. The constitution and relative configuration were determined by single-crystal X-ray diffraction analysis. In the crystal, mol-ecules are connected via O-H ⋯ O hydrogen bonds.
