Abstract
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 Δ11 isomer, in contrast to the reports of other workers who investigated Pacific codfish and found only the Δ9 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.
