Synthetic approaches to (±)- and (3S)-analogs of the AI component of the Aonidiella aurantii sex pheromone (3S)-methyl-6R-isopropenyldec-9-en-1-ylacetate based on stepwise alkylation of acetoaceticester by 3-butenylbromide and 1,5-bifunctional 3-methylpentanes were investigated.

The versatile chiral synthon methyl (R)-5,5-dimethoxy-3-methylpentanoate has been prepared for the first time via ozonolytic decyclization of (R)-4-menthenone, which is available from L-(-)-menthol. The optically pure juvenoid (S)-(+)-hydroprene can be prepared from the synthon.

A simple and efficient asymmetrical synthesis was performed of a convenient bifunctional building block, methyl (R)-5,5-dimethoxy-3-methylpentanoate and its (S)-enantiomer. The possibility was shown of its application to the synthesis of insect pheromones.
