Abstract

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.

At this point, the minor diastereomer is separated by column chromatography in 15% yield.
