Stereoselective Syntheses of Polyunsaturated Fatty Acids, 13-( S )-HODE and 15-( S )-HETE.

Polyunsaturated fatty acids and their metabolites have been reported in which their pathway has potential for the modulation of cancer cell growth. 13-( S )-HODE and 15-( S )-HETE, both of which are main metabolites of 15-LOXs, play an important role as endogenous ligands in biological systems. However, the modification of 13-( S )-HODE and 15-( S )-HETE in pharmaceutical applications has not been explored widely. Herein, we report the stereoselective syntheses of 13-( S )-HODE, 15-( S )-HETE, and its derivatives to enable the synthesis of bioactive fatty acid analogues.
