Synthesis of All Four Possible Stereoisomers of 5,9-Dimethylpentadecane, the Major Sex Pheromone Component of the Coffee Leaf Miner Moth, Perileucoptera coffeella

All of the four possible stereoisomers of 5,9-dimethylpentadecane, the major sex pheromone component of the coffee leaf miner moth (Perileucoptera coffeella), were synthesized by using the methyl esters of (S)- and (R)-3-hydroxy-2-methylpropanoic acid as chiral sources for the purpose of determining the stereochemistry of the pheromone.

Pheromone synthesis, CXCIX([≠]). Synthesis of all the stereoisomers of 7-methylheptadecane and 7,11-dimethylheptadecane, the female sex pheromone components of the spring hemlock looper and the pitch pine looper

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).
