(Z)-9-Tetradecenyl methanesulfonate derived from (Z)-9-tetradecenoic acid (myristoleic acid) of beef tallow served as starting material for the preparation of sets of alcohols, alkyl acetates, and aldehydes having 16 and 18 carbon atoms. These com pounds are known to function as pheromones in various insect species. Chain elongation of (Z)-9-tetradecenyl methanesulfonate by malonic ester synthesis follow ed by esterification afforded the methyl ester of (Z )-11-hexadecenoic acid. This ester was converted to a set of pherom ones having a C16-chain with a (Z)-double bond in position 11. Chain elongation of (Z )-11-hexadecenyl methanesulfonate yielded the m ethyl ester of (Z)-13-octadecenoic acid which was used for the preparation of a set of pheromones having a C18-chain with a (Z)-double bond in position 13. All the reaction steps involved provided excellent yields. |
