Novel synthesis of 1,3-dienes from 1-alkenes via “ene” reaction with Pummerer rearrangement product: a short synthesis of the sex pheromone of the red bollworm moth was written by Ishibashi, Hiroyuki;Komatsu, Hajime;Maruyama, Kazumi;Ikeda, Masazumi. And the article was included in Tetrahedron Letters in 1985.Formula: C14H24O2 The following contents are mentioned in the article:
The Pummerer rearrangement product, 4-ClC6H4SCH2O2CCF3, obtained from 4-ClC6H4SOMe and (CF3CO)2O, reacted with 1-alkenes in CF3CO2H to give 4-ClC6H4SCH2CH2CH:CHR [R = (CH2)4Me, (CH2)6Me, (CH2)7CO2Me], which were readily converted into CH2:CHCH:CHR by oxidation and pyrolysis. Using this method, 9,11-dodecadien-1-yl acetate, a sex pheromone of the red bollworm moth, was synthesized. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Formula: C14H24O2).
(E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Formula: C14H24O2
