SYNTHESIS OF PHEROMONES AND RELATED MATERIALS VIA OLEFIN METATHESIS
-
Paragraph 0110, (2018/09/12)
Methods for preparation of olefins, including 8- and 11-unsaturated monoenes and polyenes, via transition metathesis-based synthetic routes are described. Metathesis reactions in the methods are catalyzed by transition metal catalysts including tungsten-, molybdenum-, and ruthenium-based catalysts. The olefins include insect pheromones useful in a number of agricultural applications.

Very short synthetic routes to nine cisolefin-containing pheromones containing a variety of functionality, including an unconjugated (E,Z) diene, are reported (see scheme). These lepidopteran pheromones are used extensively for pest control, and were easily prepared using ruthenium-based Z-selective cross metathesis, highlighting the advantages of this method over less efficient ways to form Z olefins.
Stereodirectional synthesis of the main component of pheromone (9Z,12E)-tetradeca-9,12-dienyl acetate by cross-coupling

By cross-coupling of alkynyl cuprate with crotyl halides was synthesized (9Z,12E)-tetradeca-9-12-dienyl acetate, the main component of pheromones of several insect species Lepidoptera. The assignment of the chemical shifts of diene system was performed by 1H and 13NMR spectroscopy.
