Crystal structure of (-)-(S)-4-[(2 S,3 S,4 S, Z)-3-hydroxy-4-methyl-hept-5-en-2-yl]-1,3-dioxolan-2-one

The title compound, C₁₁H₁₈O₄, consists of an anti,anti,anti-stereo-tetrad with a 1,2-carbonate and an alkene motif. The mol-ecule displays a common zigzag conformation. The five-membered ring has a twisted conformation on the C-C bond. In the crystal, a strong inter-molecular hydrogen bond between the hy-droxy group and the carboxyl-ate moiety from an adjacent mol-ecule forms chains propagating along the b-axis direction. The absolute structure of the mol-ecule in the crystal was determined by resonant scattering [Flack parameter = 0.05 (6)].
