Kolbe Synthesis of Unsaturated Pheromones by Coelectrolysis with 5-Alkynoic Acids
Seidel, Wolfgang,Schaefer, Hans J.
, p. 3898 - 3903 (2007/10/02)
The alkynoic acids 5a - g are synthesized by coelectrolysis of 5-alkynoic acids 2a - c with dicarboxylic monoesters 3a - d.By reduction, Lindlar-hydrogenation, and acetylation these are converted into pheromones such as (Z)-11-hexadecenyl acetate (7b), the pheromone of Mamestra brassicae. 2a - c can be prepared by alkynylation of 1-bromo-3-chloropropane to 1a - c, substitution by cyanide and hydrolysis.
