Fatty acids of the n-3 and n-6 families containing a photoactive conjugated tetraene group near the carboxylate were prepared from several naturally occurring fatty acids by sequential iodolactonization and treatment with excess 1,8-diazabicyclo[5.4.0]undec-7-ene. The new conjugated fatty acids include 5E,7E,9E,11Z,14Z- and 5E,7E,9E,11E,14Z-eicosapentaenoic acids derived from arachidonic acid; 5E,7E

There is provided a novel chemical synthetic method for the preparation of a 5-oxo-ETE and related compounds. The method is based on a short and efficient synthesis of 5-oxo-ETE from commercially available Arachidonic acid. The method is based on the surprising discovery that a 5-oxo-conjugated fatty acid may be efficiently converted into the corresponding 5-oxo-conjugated fatty acid by reaction with the Dess-Martin reagent (1,1,1-triacetoxy-1,1-dihydro-1,2-benziodoxol-3(1H)-one)in the presence of pyridine or a substituted pyridine.
