A stereospecific synthesis of 12-acetoxy-1,3-dodecadiene, the sex pheromone of Diparopsis castanea (Hampson) was written by Cardillo, Giuliana;Orena, Mario;Porzi, Gianni;Sandri, Sergio. And the article was included in Gazzetta Chimica Italiana in 1980.COA of Formula: C14H24O2 The following contents are mentioned in the article:
(E)-CH2:CHCH:CH(CH2)8OR (I; R = Ac), the pheromone of the red bollworm moth, was stereospecifically prepared by alkylation of THPOCH2CCH (II, THP = tetrahydropyranyl) and successive LiAlH4 reduction Thus, reaction of equimolar THPO(CH2)8I with II, BuLi, and (Me2CH)2NH in THF gave 80% R1O(CH2)8CCCH2OR1 (III; R1 = THP), which was hydrolyzed over Amberlyst H-15 in MeOH to give 92% diol (III; R1 = H) (IV). Reduction of 20 mmol IV with LiAlH4 gave 95% HO(CH2)8CH:CHR2 (V; R2 = CH2OH), which (10 mmol) was oxidized with MnO2 in CH2Cl2 to give quant. aldehyde (V; R2 = CHO) (VI). Methylenation of 10 mmol VI with Hg, Mg, and CH2I2 in Et2O at room temperature gave 83% I (R = H), which (5 mmol) was acetylated in pyridine at 0° to give 98% I (R = Ac). 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. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. 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.COA of Formula: C14H24O2
