Synthesis of (1R,3S,5S)-1,3,8-trimethyl-2,9-dioxabicyclo[3.3.1]non-7-ene, the male pheromone of a hepialid moth Endoclita excrescens, and its enantiomer
Both (1R,3S,5S)- and (1S,3R,5R)-isomers of 1,3,8-trimethyl-2,9-dioxabicyclo[3.3.1]non-7-ene were synthesized by starting from (S)- and (R)-isomers of ethyl 3-hydroxybutanoate, respectively. The (1R,3S,5S)-isomer was identified as the male sex pheromone of a Japanese hepialid moth, Endoclita excrescens.
