Summary: | Natural sources of cis-n-eicos-11-enoic acid, a convenient method of isolating the acid, and its conversion to the trans-form are described. It was found that the principal eicosenoic acid of a sample of Atlantic cod liver oil (Gadus callarias) was the Δ 11 isomer, in contrast to the reports of other workers who investigated Pacific codfish and found only the Δ 9 isomer. The following derivatives are reported: cis-n-eicos-11-enoic anilide, N-hydroxyamide, epoxide, chlorohydrin; 11,12-dihydroxyeicosanoic acid (low-melting isomer), and its amide; trans-n-eicos-11-enoic acid, its hydrazide, and N-hydroxyamide. Some new physical constants of the cis-acid and its methyl ester are given. |
