- Stereospecific synthesis of (2E,13Z)-2,13-octadecadienyl acetate, the sex pheromone component of the Lepidoptera species
-
The main component of the sex pheromone of many lepidopteran pests, (2E,13Z)-2,13-octadecadienyl acetate (1), has been synthesized following a simple route using 12-(2-tetrahydropyranyloxy)-1-dodecyne (2) as the starting material. Copyright Taylor & Francis Group, LLC.

- Synthesis from 10-undecenoic acid of octadeca-2E,13Z-dienylacetate, a component of the sex pheromones of Synanthedon tipuliformis and Zenzera pyrina
-
A new synthesis of octadeca-2E,13Z-dienylacetate from 10-undecenoic acid is developed by constructing the carbon framework of the pheromone in the key step and introducing the 2E double bond by Doebner condensation of hexadec-11-ynal and malonic acid.

(equation presented) A new, convergent synthesis of (E,Z)-2,13-octadecadienyl acetate (1) and (E,Z)-3,13-octadecadienyl acetate (2), the two key components of the leopard moth Zeuzera pyrina, from 2-chloromethyltetrahydrofuran in good overall yields and stereomeric purity is reported. The synthesis of both components utilizes the common intermediate sulfone 12 as a convenient building block to be coupled with iodoacetylenic derivatives 9 or 17 in the key step.

A convergent synthesis of octadeca-2E,13Z-dienyl acetate, a pheromone component of Synanthedon tipuliformis C., has been developed. The synthesis is based on cross-coupling of 8-iodooct-2E-en-1-ol THP ether with dec-57-enyl bromide catalyzed by CuBr.

-
The Wittig-Horner reaction of ethoxycarbonylmethylenetriphenylphosphorane or ethyl diethylphosphonoacetic acid with cis-11-hexadecenal and the modified Knoevenagel reaction of this aldehyde with malonic acid gave the ethyl ester of trans-2,cis-13-octadecadienoic acid and trans,cis-13-octadecadienoic acid, which upon reduction and acetylation were converted into trans-2,cis-13- and trans-3-cis-13-octadecadien-1-yl acetates, which are components of the sex pheromone of Synanthedon tipuliformis (Lepidoptera, Sisiidae).

- A CONVENIENT SYNTHESIS OF 2,13- AND 3,13-OCTADECADIENYL ACETATES, SEX PHEROMONE COMPONENTS OF THE Synanthedon SPECIES
-
The sex pheromone components of several Synanthedon species, 2,13- and 3,13- octadecadienyl acetates (Ic, Id, IIc, IId), have been synthesized following the acetylenic route of chain elongation.Starting from ω-alkyn-1-ols III, the final compounds were constructed in five steps in about 30percent overall yields.Transformation of triple bond containing intermediates into the corresponding (Z)- and (E)-olefins was achieved either by hydrogenation over the P2-Ni catalyst or by using a dispersion of sodium in toluene.The title pheromones were generated in more than 97percent stereoisomeric purity. 1H and 13C NMR data of all derivatives are included.
