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

Abstract

The title compound, C11H18O4, consists of ananti,anti,anti-stereotetrad with a 1,2-carbonate and an alkene motif. The molecule displays a common zigzag conformation. The five-membered ring has a twisted conformation on the C—C bond. In the crystal, a strong intermolecular hydrogen bond between the hydroxy group and the carboxylate moiety from an adjacent molecule forms chains propagating along theb-axis direction. The absolute structure of the molecule in the crystal was determined by resonant scattering [Flack parameter = 0.05 (6)].
