A Novel Synthesis of (5Z,8Z,11Z,14Z,17Z)-5,8,11,14,17-Eicosapentaenoic Acid and Its Acetylenic Precursor

A novel procedure of synthesis of (5Z,8Z,11Z,14Z,17Z)-5,8,11,14,17-eicosapentaenoic (timnodonic) acid and its acetylenic precursor, 5,8,11,14,17-eicosapentaynoic acid was developed.It uses polyacetylene strategy and a known reaction of cross-coupling between propargyl units and ω-acetylenes in the presence of copper(I) and sodium iodides and involves the in situ formation of organocopper compounds and propargyl iodides. - Key words: (5Z,8Z,11Z,14Z,17Z)-5,8,11,14,17-eicosapentaenoic acid; 5,8,11,14,17-eicosapentaynoic acid; polyacetylenic alcohols; cross-coupling
