The synthesis of four stereoisomers of the female-produced sex pheromone of the rice moth (Corcyra cephalonica) was achieved by starting from (R)-2a, (R)- or (S)-3a, and (R)- or (S)-4 and using alkylation of alkyl phenyl sulfones as the coupling reaction.Behavioral bioassy of each isomer revealed (2R,6R,10R)-1a to be eight times more active than a diastereomeric mixture of equal amounts of the eight possible stereoisomers, indicating that (2R,6R,10R)-1a is probably the natural pheromone or at least themajor component of the female blend.Electrophysiological bioassy also confirmed the high activity of (2R,6R,10R)-1a.

(2R,5S)-2-Methyl-5-hexanolide and its antipode were synthesized in highly optically pure state (98-99percent e.e.) starting from ethyl (S)-lactate and the enantiomers of methyl β-hydroxyisobutyrate.The specific rotations of our samples were D +/- 91.0 -93.5 deg (CHCl3), while the reported values of the samples prepared by resolution or asymmetric synthesis were +/- 64.5-65.6 deg.
