The interaction of Li derivatives of acetylcyclopropane cyclohexylimine with ethylene, propylene, and isoprene oxides leads efficiently to the corresponding gamma-cyclopropylketols. The cyclopropylcarbinol corresponding to the first of them is smoothly converted under the action of the couple Me3SiBr/ZnBr2 to a linear E-C7-homoallyl bromide, which is then used in the stereocontrolled synthesis of tridec-4E-enyl and trideca-4E, 7Z-dienyl acetates - components of the sex pheromones of some Lepidoptera species.
