Practical, stereoselective synthesis of Cecropia juvenile hormone

The high-yield, stereoselective conversion of geraniol (3,7-dimethyl-trans-2,6-octadien-1-ol) to the insect juvenile hormone, methyl 12,14-dihomojuvenate (methyl cis-10-epoxy-3,11-dimethyl-7-ethyl-trans, trans-2,6-tridecadienoate), has been performed by means of a nine-step route that avoids chromatography of intermediates.
