Meinwald, J. et al. published their research in Tetrahedron Letters in 1973 | CAS: 37905-02-5

(2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5) 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.Formula: C12H18O3

Chemical defense mechanisms of arthropods. XXXVI. Stereospecific synthesis of gyrinidal, a norsesquiterpenoid aldehyde from gyrinid beetle was written by Meinwald, J.;Opheim, K.;Eisner, T.. And the article was included in Tetrahedron Letters in 1973.Formula: C12H18O3 The following contents are mentioned in the article:

(E,E)-AcOCH2CH:CMe(CH2)2CH:CMeCHO, prepared by SeO2 oxidation of geranyl acetate, was coupled with the di-Li salt of MeCH(OH)C:CH to give an acetylenic triol, which when treated with Na-NH3(1)-THF followed by oxidation (MnO2) gave (E,E,E)-MeCOCH:CH-COCMe:CH(CH2)2CMe:CHCHO (gyrinidal). This study involved multiple reactions and reactants, such as (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5Formula: C12H18O3).
