Abstract

The enantioselective synthesis of both (4__R__,5__R__)‐ and (4__S__,5__S__)‐4‐methyl‐5‐nonanol (1) was achieved by starting from an optically active epoxide 5. A GC comparison on a chiral stationary phase of the synthetic enantiomers of 1 with the naturally occurring 1 was executed, and (4__S__,5__S__)‐1 was shown to be identical with the natural 1 isolated as the male‐produced pheromone compound of the weevils Rhynchophorus vulneratus and Metamasius hemipterus.
