A stereoselective synthesis of the title compound (II) as well as that of its lowerhomolog, 6-ethyl-10-methylundeca-5-trans, 9-dien-2-one (III), was accomplished. Both were converted to methyl dl-12,14-dihomojuvenate (dl-C18-Cecropia juvenile hormone, I) and methyl dl-14-homojuvenate (IV), respectively. Analogs of the Cecropia juvenile hormones with an ethynyl substituent (XVIII and XIX) were also
