Efficient and Stereoselective Synthesis of 10-Hydroxy-4,8-dimethyldeca-3(E),8(E)-dienoic Acid, a Precursor to (3E,8E)-Suspensolide, Anastrephin, and Epianastrephin was written by Battiste, Merle A.;Wydra, Roman L.;Strekowski, Lucjan. And the article was included in Journal of Organic Chemistry in 1996.Name: (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate The following contents are mentioned in the article:
The stereoselective synthesis of 10-hydroxy-4,8-dimethyldeca-3(E),8(E)-dienoic acid has been accomplished in a four-step sequence from geranyl acetate with an overall yield of 30%. This study involved multiple reactions and reactants, such as (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5Name: (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate).
(2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. 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.Name: (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate
