Stereoselective synthesis of both (5S,6R)-(+)- and (5R,6S)-(−)-6-acetoxy-5-hexadecanolides, the major component of a mosquitoovipositionattractantpheromone, was achieved from (S)-2-cyclohexen-1-ol.

Total syntheses of 5-hexadecanolide (1), 6-acetoxy-5-hexadecanolide (2) and tanikolide (3) are described. 1-Bromoundecane (4) and 5-benzyl-1-pentanal (5) were chosen as starting materials. Wittig olefination and Grignard addition 4 and 5 afforded the 16-carbon skeleton, which under went a series of functional group transformations to give δ-lactonederivatives 1, 2 and 3.

Both (5S, 6R)-(+)- and (5R, 6S)-(−)-6-acetoxy-5-hexadecanolide, the ovipositionattractantpheromone of the mosquitoCulexpipiensfatigans, were synthesized employing the Sharpless asymmetric epoxidation as the starting step.

accomplished from readily available hex-5-yn-1-ol via Shi’s asymmetric epoxidation as the key step, in eight steps with an overall yield of 33.5%. In addition, the stereoselective synthesis of all fourisomers of 6-acetoxy-5-hexadecanolide 1a–1d were obtained via Sharpless asymmetric dihydroxylation and Mitsunobu reaction as the key steps with overall yields of 16.5–21.2%, respectively.
