General method for the synthesis of 1,3-dienes. Simple syntheses of β- and trans-α-farnescene from farnesol was written by Tanaka, Shin;Yasuda, Arata;Yamamoto, Hisashi;Nozaki, Hitosi. And the article was included in Journal of the American Chemical Society in 1975.COA of Formula: C14H24O2 The following contents are mentioned in the article:
The first highly stereo- and regioselective procedure for the transformation of allylic alcs. into 1,3-dienes is described. The method involves epoxidation of allylic alcs. with tert-butyl hydroperoxide-V catalyst followed by trimethylsilylation, diethylaluminum 2,2,6,6-tetramethylpiperidide (DATMP)-promoted oxirane ring opening producing 3-ene-1,2-diols stereo- and regioselectively, and deoxygenation of 1,2-diols through dibromides by PBr3-Cu2Br2-Zn. Thus, nerol, geraniol, (Z,E)-farnesol, and (E,E)-farnesol were converted into β-myrcene, trans-β-ocimene, β-and trans-α-farnesene, resp. AcO(CH2)8CH:CHCH:CH2, a sex pheromone isolated from the female red bollworm moth was also prepared by this method. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7COA of Formula: C14H24O2).
(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. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.COA of Formula: C14H24O2
