A novel palladium-catalyzed deoxygenation of ene diols to 1,3-dienes was written by Trost, Barry M.;Tometzki, Gerald B.. And the article was included in Synthesis in 1991.Quality Control of (E)-Dodeca-9,11-dien-1-yl acetate The following contents are mentioned in the article:
Hydroxylative Knoevenagel condensation of aldehydes followed by reduction provides a simple entry to 1,4-ene diols e.g. I (R = H). Subjecting the dicarbonate e.g. I (R = CO2Me) to a Pd catalyst in the presence of (Me2CHO)3P achieves a mild vinylogous deoxygenation to (E)-1,3-dienes, e.g. II. Stereocontrolled synthesis of the sex pheromone of the red bollworm moth, (E)-9,11-dodecadienyl acetate, and a formal synthesis of the cotton boll weevil antifeedant, α-eleostearic acid, demonstrate the utility of this new methodol. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Quality Control of (E)-Dodeca-9,11-dien-1-yl acetate).
(E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. 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 (E)-Dodeca-9,11-dien-1-yl acetate
