Cruentol I (4S,5S)-5-Methyl-4-octanol I Palmetto weevil I Pheromones I Rhynchophorus cruentatm
Cruentol [ (4S,5S)-l], the male-produced aggregation pheromone of Rhynchophorus cruentatus, was synthesized by star-ting from the epoxy alcohol 3 obtained by lipase-catalyzed asymmetric hydrolysis of the meso-diacetate 2.
