The four isomers of 6,11-hexadecadien-1-ol, their acetates, and the corresponding aldehydes were obtained by a common scheme based on the alkylation of 5-hexyn-1-ol by the tetrahydropyranyl ether of 1,5-pentamethylene bromohydrin, stereoselective reduction of the triple bond in the alkylation product 11-(2-tetrahydropyranyloxy)-5-undecyn-1-ol, oxidation of the obtained Z or E isomer of 11-(2-tetrahydropyranyloxy)-5-undecen-1-ol to the aldehyde, and stereoselective olefination of the latter with pentylidenetriphenylphosphorane under the conditions of the formation of a doubl e bond with a specific (Z or E) configuration of the substituents.Subsequent removal of the tetrahydropyranyl protection of the alcohol group in the Wittig reaction products by acid hydrolysis gave 6,11-hexadecadien-1-ols, the acetylation or oxidation of which led to the corresponding acetates or aldehydes.The latter are components of the sex pheromones of insects of the Saturniidae family.
