(2SR,3SR)-Isopropyl 3-{[dimethyl(phenyl)silyl]methyl}-2-hydroxy-2-vinylpent-4-enoate

The relative configuration of the title compound, C19H28O3Si, which was synthesized using a dienolate-[2,3]-Wittig rearrangement, was corroborated by single-crystal X-ray diffraction analysis. The Si—C bond distances are in the range 1.858 (2)–1.880 (2) Å and an intramolecular O—H⋯O hydrogen bond helps to stabilize the molecular conformation.
