Tolstikov,Dzhemilev,Khusnutdinov
, p. 101 - 102 (1978)
The synthesis of the sex attractant of the codling moth Laspeyresia pomonella has been performed using as the initial compounds linear dimers of butadiene with methyl acrylate.
Synthesis of dodeca-8E,10E-dien-1-ol - The sex pheromone of Laspeyresia pomonella via the acetolysis of 4-propenyl-1,3-dioxane

, p. 582 - 584 (1996)
A new scheme has been developed for the synthesis of dodeca-8E,10E-dien-1-ol (the sex pheromone of the codling moth) from sorbyl acetate, available from 4-propenyl-1,3-dioxane through the intermediate diacetate of 3-propenyl-2-oxapentane-1,5-diol.

A convenient procedure allowing iron-catalyzed cross-coupling of alkyl or aryl Grignard reagents and conjugated dienyl bromides is reported, relying on the use of cheap and non-toxic magnesium alkoxides as sole additives. An excellent stereoselectivity is observed in the alkyl-dienyl series. This sequence has been applied to the synthesis of the sex pheromone of codling moth, illustrating its applicability for obtaining targets of industrial interest. Preliminary mechanistic studies carried out on the aryl-dienyl cross-coupling suggest that in situ generated ate homoleptic organoiron(II) species act as catalytically relevant intermediates. A modified preparative method for the realization of THF solutions of dienyl bromides as “ready-to-use” coupling partners is also discussed, circumventing the thermal instability of those derivatives.
SYNTHESIS OF PHEROMONES AND RELATED MATERIALS VIA OLEFIN METATHESIS
-
, (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.
SYNTHESIS OF OLEFINIC ALCOHOLS VIA ENZYMATIC TERMINAL HYDROXYLATION

Paragraph 0315; 0320, (2016/01/30)
In certain aspects, the present invention provides methods for producing terminally hydroxylated alkenes and alkynes by contacting an unsaturated or saturated hydrocarbon substrate with a hydroxylase enzyme. Exemplary terminal hydroxylases useful for carrying out the methods of the invention exhibit strong selectivity towards one terminal carbon of a hydrocarbon substrate and include, but are not limited to, non-heme diiron alkane monooxygenases, cytochromes P450 (e.g., cytochromes P450 of the CYP52 and CYP153 family), as well as long chain alkane hydroxylases. In some embodiments, the terminally hydroxylated alkene or alkyne is further converted to a terminal alkenal. In certain embodiments, terminally hydroxylated alkenes and alkynes are useful as insect pheromones which modify insect behavior. In other embodiments, terminally hydroxylated alkenes and alkynes are useful intermediates for producing pheromones via acetylation or oxidation of the alcohol moiety.
