(2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5) 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. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Quality Control of (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate

Chemical transformation of terpenoids. X. Ionophoretic activities of macrocyclic lactone epoxides synthesized from geraniol was written by Shibuya, Hirotaka;Ohashi, Kazuyoshi;Narita, Norihiko;Ishida, Toshimasa;Kitagawa, Isao. And the article was included in Chemical & Pharmaceutical Bulletin in 1994.Quality Control of (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate The following contents are mentioned in the article:

Two coronand-type 18-membered lactone epoxides, i.e., geranyl dimeric lactone diepoxide (GL2E2, I) and tetraepoxide (GL2E4, II), were synthesized from geraniol as diastereomeric mixtures Among them, II was shown to exhibit ion-transport activity for Ca2+ ion in the test using a W-07 (liquid-membrane type) apparatus and ion-permeation activities for Ca2+ and K+ ions across the human erythrocyte membrane. Isolation of six component diastereomers of II was effected by HPLC separation of two diastereomeric tetraepoxides, III and IV which were prepared from two diepoxides I. The relative stereostructures of these diastereomers were determined by a combination of X-ray diffraction and 1H-NMR analyses. Among the six diastereomers, S2-sym. V exhibited the strongest ion-transport activity for Ca2+ ion while C2-sym. GL2E4-6 VI exhibited the strongest ion-permeation activity for Ca2+ ion across the human erythrocyte membrane. This study involved multiple reactions and reactants, such as (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5Quality Control of (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate).
