(10E,12E,14E)-9,16-Dioxoocta­deca-10,12,14-trienoic acid

L. Bréant, C. Vonthron-Sénécheau, L. Brelot and A. Lobstein

Abstract: The title octa­deca­trienoic acid derivative, C18H26O4, was isolated from Silene maritima With. (Caryophyllaceae), the first time this natural compound has been found in the Caryophyllales order. This fatty acid has an 18-carbon backbone with three double bonds on trans (E) conformation and two carbonyl. In the crystal, molecules are linked via pairs of O-H...O hydrogen bonds, forming inversion dimers.
