Insect pheromones and their analogues XXV. Synthesis of acetylenic precursors of pheromones from undecylenic acid

The selective ozonolysis of pentadec-1-en-12-yne and heptadec-1-en-12-yne, synthesized from the readily available undecylenic acid, has given tetradec- and hexadec-11-yn-1-ols — acetylenic precursors of a number of pheromones of insects of the order Lepidoptera.Institute of Chemistry, Bashkir Scientific Center, Urals Branch, Academy of Sciences of the USSR, Ufa.
