(S)-6-Methyl-3-octanone, a component of the alarm pheromone of Grematogaster ants, was synthesized through a key step of stereoselective Michael addition reaction using (4S)-4-benzyloxazolidinone as chiral auxiliary. The target product was obtained with an overall yield of 43.0% over six steps in high enantiomeric purity.
