The ester enolate Claisen rearrangement of (R)-1-methyl-(E)-2- butenyl hydroxaacetate provides complete asymmetric transfer along with 98percent 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.
