Disparlure, cis-7,8-epoxy-2-methyloctadecane, was identified as the female-produced sex pheromone of the gypsy moth, Lymantria &spur L., by Bierl, Beroza and Collier.' The 7R,BS enantiomer of disparlure was synthesized by Marumo' and Mori 3 and found to be more attractive to males than the racemate.
rs,3'S,4'R,2Z)-(-)-2-(Y,4'-Epoxy-4'-methylcyelohexyl)-6-methyl-2,5-heptadiene, a sex pheromone component of the southern green stink bug (Nezara viridula (L.)), was synthesized stereoselectively in four steps and 18% overall yield from (S)-4-methyl-3-cyclohexene-l-carboxylie acid.
