The esterenolateClaisenrearrangement of (R)-1-methyl-(E)-2-butenyl hydroxyacetate provides complete asymmetric transfer along with 98% erythroselectivity to give (2R,3S)-2-hydroxy-3-methyl-(E)-4-hexenoic acid. Its synthetic utility is demonstrated by the stereocontrolled synthesis of optically active pheromones.
