(2R,4S,5S)-5-Hydroxy-4-methyl-3-oxohept-6-en-2-yl benzoate

Abstract

The title compound, C15H18O4, which crystallizes with two mol­ecules in the asymmetric unit, was obtained in the course of the total synthesis of curvicollides A–C and fusaequisin A. It features the relative configuration of the Western aldol part of the natural products. In the crystal, mol­ecules are linked by C—H...O hydrogen bonds.
