Insect pheromones and their analogs. XV. The synthesis of 9-oxodec-2E-enoic acid — A pheromone of the honeybeeApis melliferana
A new effective route to the synthesis of 7-oxooctanal has been found which is based on the ozonolysis of the tetrahydropyran-2-yl ether of 7-methyloct-7-en-l-ol — the product of the coupling of the readily available methallyl chloride and the Grignard reagent from the corresponding ether of 5-bromopentan-l-ol. From the 7-oxooctanal has been obtained 9-oxodec-2E-enoic acid — a pheromone of the honeybeeApis melliferana.
