The isolation and structure determination of eldanolide, the wing gland pheromone of the male African Sugar Cane Borer, Eldana saccharina (Wlk.) is described. The absolute configuration was determined as (3S, 4R) by comparison of the CD spectra of the natural pheromone with both synthetic enantiomers.
A stereoselective synthesis of (+)-eldanolide and (-)-cis-whisky lactone in optically pure forms has been achieved by employing a regioselective fragmentation reaction of the gamma-halo esters as a key step.
