Methyl 2‐hydroxy‐2‐[5′‐hydroxy‐5′‐(1‐hydroxy‐1‐methyl­ethyl)‐5,2′‐di­methyl­per­hydro‐2,2′‐bi­furan­yl‐5‐yl]­acetate

The relative configuration was determined for the title compound, C₁₆H₂₈O₇, which was obtained as a mixture of epimers. There are both intra‐ and intermolecular hydrogen bonds, the latter forming dimers around the crystallographic centres of inversion.
