(±)-Methy1 8-epi-nonactate ((±)-) and (±)-methy1 nonactate ((±)-) were derived from (±)-7-oxa-2-bicyclo[2.2.1]heptanone () in four and five synthetic steps, respectively.

In four synthetic steps, (+)- and (–)-methyl 8-epinonactate ((+)- and (–)−4) have been derived from (+)- and (–)-7-oxabicyclo[2.2.1]heptan-2-one ((+)- and (–)−9), respectively. The (+)- and (–)-methyl nonactate ((+)- and (–)−3) were obtained from (+)- and (–)−4, respectively, by Mitsunobu displacement reactions.
