A highly stereoselective synthesis of (E)-1-substituted-1,3-dienes was written by Bloch, R.;Abecassis, J.. And the article was included in Tetrahedron Letters in 1982.Product Details of 50767-78-7 The following contents are mentioned in the article:
Alkylation of sulfone I (R = H) with RCH2I [R = H, Bu, (CH2)7OR1 (R1 = tetrahydropyranyl)] gave I [R = Me, (CH2)4Me, (CH2)8OR1] (II). Thermolysis of II in the vapor phase at 600-650° gave the corresponding (E)-RCH:CHCH:CH2 (III) stereospecifically and in 85, 90, and 80-85% yield, resp., by retro-Diels-Alder reaction and in situ SO2 extrusion. III [R = (CH2)8OAc] is a component of the sex pheromone of the red bollworm moth. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Product Details of 50767-78-7).
(E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Product Details of 50767-78-7
