the four stereoisomers of 1,7-dimethylnonyl propanoate, the female sex pheromone of the western corn rootworm (Diabrotica virgifera virgifera LeConte), was synthesized in four different ways by employing one of the following four reactions as the key step: (i) crossmetathesis using the Grubbs I catalyst, (ii) crossmetathesis using the Grubbs II catalyst, (iii) alkylation of an alkynide anion, and
