Lithium acetylides in the presence of BF3·Et2O react with epoxyalcohols derived from (E)-allylic alcohols to give erythro-1,2-diols, a reactionused successfully in the stereoselective synthesis of erythro-hexadecan-5-olide.
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.

An asymmetric total synthesis of (-)-6-acetoxy-5-hexadecanolide has been accomplished by employing a seven-step sequence. Asymmetric α-benzoyloxylation of dodecanal followed by indium-mediated one-pot allylation produces the anti-1,2-diol. The six-membered lactone ring is constructed by RCM reaction.
Compounds of formula (II)
in which R' represents an alkyl group of 6 to 12 carbon atoms, are of value as mosquito attractants, mosquitoes being attracted to a location where they and/or their eggs or larvae are then destroyed.
式 (II) 中 R' 代表 6 至 12 个碳原子的烷基的化合物具有诱蚊作用,可将蚊子吸引到一个地方,然后在那里消灭它们和/或它们的卵或幼虫。
