(1S,4R,5R)-(+)-α-Acoradiene [1,8-dimethyl-4-(1-methylethenyl)spiro[4.5]dec-7-ene] (1) is shown by its synthesis to be the major component of the male-produced aggregation pheromone of the broad-horned flour beetle (Gnatocerus cornutus).
Examples are given to illustrate the use of chemical and/or enzymatic asymmetric reactions in the synthesis of the new pheromones of the broad-horned flour beetle, flea beetle, currant stem girdler and Colorado potato beetle. The relationships between stereochemistry and bioactivity among pheromones are summarized to emphasize biodiversity as revealed in pheromone perception.
