(2S,3R,4R,5R)-2-(tert-Butyl­dimethyl­silyloxymeth­yl)-2,4,5-trimethyl­tetra­hydro­furan-3,4-diol

In the title compound, C₁₄H₃₀O₄Si, the bond angles around Si are in the range 105.4 (3)–112.1 (4)° and the tetra­hydro­furan ring adopts a distorted envelope conformation. There is one intra­molecular and one inter­molecular O—H...O hydrogen bond in the crystal structure. A spiral of mol­ecules forms around the 4₁ axis (c axis) of the crystal structure via the inter­molecular O—H...O hydrogen bond.
