A convenient synthesis of cis mono-olefinic pheromone components I, II, and III has been achieved starting from (Z)-5-(2-tetrahydropyranyloxy)-pent-2-yn-1-ol (V) and (Z)-7-(2-tetrahydropyranyloxy)-hept-2-yn-1-ol (IV), both of which have been obtained from a common intermediate, viz. the dianion of prop-2-yn-1-ol.
