Abstract: A synthesis of hepoxilins (HX) B₃, mediators of the insulin release from pancreas, has been carried out by a new route via polyacetylenic intermediates. The configurations of hydroxyl group in epimeric HXB₃ were determined. (10R, 11R, 12S)-Diastereomer of HXB₃ and its methyl ester are more polar on silica gel, and Bu^tMe₂Si-ether of the latter is less retentive in GLC than the corresponding (10S)-diastereomeric derivatives.
