✦ Synopsis

Four stereoisomers (1a-d) of (±)-3-methyl-α-himachalene produced sex pheromone of the sandfly Lutzomyia longipalpis was shown to possess the structure and relative were synthesized by employing the intramolecular Diels-Alder reaction of (±)-14 to (±)-18 as the key-step. The male-configuration as depicted in 1c.
