Abstract: (R,4S)-4-Methyl-3-hexanol and ( 3R,4S )-4-methyl-3-heptanol, which are the pheromones of ant Tetramorium impurm and Leptogenys diminuta, were stereoselectively synthesized by six-step sequence starting from N-bornane-10,2-sultam separately, the two asymmetric carbon atoms of the target products were created by employing asymmetric syn aldolization of N-acylbornane-10,2-sultam with propylaldehyde. The enantiomeric excess of the target products prepared by this route is over 92%.

Key words: Pheromone, Asymmetric syn-aldolization, N-Bornane-10,2-sultam
