Synthesis of the enantiomers of 21-methyl-7-hentriacontanone and a stereoisomeric mixture of 5-acetoxy-19-methylnonacosane, candidates for the female sex pheromone of the screwworm fly, Cochliomyia hominivorax

The enantiomers of 21-methyl-7-hentriacontanone (1), which might show weak bioactivity as the female sex pheromone of the screwworm fly (Cochliomyia hominivorax), were synthesized by starting from the enantiomers of citronellal. (±)-Citronellol was converted to a racemic and diastereomeric mixture of 5-acetoxy-19-methylnonacosane (2), which was considered to be a candidate for the female sex pheromone of C. hominivorax. Synthetic 2 exhibited no pheromone activity against male C. hominivorax.

All the stereoisomers of 7-methylheptadecane (1) and 7,11- dimethylheptadecane (2) were synthesized by starting from the enantiomers of citronellol (3) and methyl 3-hydroxy-2-methylpropanonate (8), respectively. A short synthesis of meso-7,11-dimethylheptadecane [(7R, 11S)-2] was achieved starting from meso-2,6-dimethylheptanedioic acid [(2R,6S)21]. A mixture of (S)-1 and (7R, 11S)-2 is the pheromone of the spring hemlock looper moth (Lambdina athasaria) and the pitch pine looper moth (L. pellucidaria).
