All the cis n-octadecenoic acids (A2-A 17) have been synthesised along with several dodecenoic (AT-All), dodecynoic (A7-All), and octadecynoic (A 2, A4-A 12) acids required as intermediates. ## Discussion \* Part 12, J. Chem. Soe. (1963) 5772. \* Unless otherwise indicated the purity of all este

The synthesis of all isomeric Cta furan-containiaag fatty acids from furan, furfura~ or methyl octadc~ynoate is described. ## A. 2,5-Epoxyoctadeca-2,4-dienoic acid (1) 1. 2.Trldec-l '-enylfuran A mixture of 1.bromododecane (43.7 g, 3.t75 reel), triphenylphosphine (46 g,
The N.M.R. spectra of the cis octadecenoic (A2-A17), octadecynoic (A2-A 5, AlΒ°), and dodecynoic (A s\_ A ll) acids have been recorded. Those with unsaturation near the centre of the molecule cannot be distinguished from one another but the four isomers with unsaturation closest to the carboxyl group
All the cis octadecenoic esters have been converted to cyclopropane compounds by reaction with zinc-copper couple and di-iodomethane. Their gas-liquid chromatographic behaviour on four liquid phases is described. Six isomers (2,3-; 3,4-; 4,5-; 15,16-; 16,17 -; and 17,18 -) have distinctive nuclear m
Acetylenic compounds especially acetylenic fatty acids (Cl, to Cz1) were first of all identified in higher plants. Their structure is very different with regard to the number of the double and triple bonds per molecule, and the functional groups. The mechanism of the biogenesis and the influencing
