(4S,5S,6R,E)-3,5-Dimethyl-6-vinyl­hept-2-ene-1,4,7-triol

The title compound, C11H20O3, was obtained in the course of the total syntheses of curvicollides A–C and features the same relative configuration for the central lactone moiety as that reported for the latter compounds. In the crystal, mol­ecules are linked via O—H⋯O hydrogen bonds: all of the OH groups act as donors as well as acceptors for these bonds, hence each mol­ecule is bound to six surrounding mol­ecules and a three-dimensional network is formed. The absolute structure was confirmed by refinement of the Flack parameter.
