Total chemical syntheses of the rare natural ω-3 C18 and C20 fatty acids, which possess potential antiinflammatory activity, were elaborated for subsequent studies of their biological activity.

Three fatty acids were synthesized from commercially available α-linolenic, stearidonic and eicosapentaenoic acids by C2-elongation using a four step preparative technique. The parent fatty acid methyl esters were reduced to alcohols with LiAlH4, converted to bromides by treatment with triphenylphosphine dibromide, coupled with a lithiated C2-elongation block - 2,4,4-trimethyl-2-oxazoline - to form the corresponding 2,2-dimethyloxazolines of C2-elongated fatty acids, and finally, converted to the target polyunsaturated fatty acids by acidic alcoholysis. Yields of more than 60% were achieved on a gram scale. The resulting 11Z,14Z,17Z-eicosatrienoic, 8Z,11Z,14Z,17Z-eicosatetraenoic and 7Z,10Z,13Z,16Z,19Z-docosapentaenoic acids were obtained as colorless oils with >98% purity and could be used for biochemical investigations without additional purification. The elongated fatty acids were free of byproducts that could result from Z-E isomerization or migration of double bonds.
