Stereoselective syntheses of E- and Z-9,11-dodecadien-1-yl acetates: the major sex pheromones of the red bollworm moth was written by Ochiai, Masahito;Ukita, Tatsuzo;Fujita, Eiichi. And the article was included in Chemical & Pharmaceutical Bulletin in 1983.Electric Literature of C14H24O2 The following contents are mentioned in the article:
The key step of the title syntheses was the olefination reaction of E– and Z–I (R = CH2SO2Ph) to give the corresponding dienes I (R = CH:CH2). This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Electric Literature of C14H24O2).
(E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
