Synthese und biologische Eigenschaften der 14,15-Didehydroleukotriene und ihrer Methylester Syntheses and Biological Activities of 14,15-Didehydroleukotrienes and their Methyl Esters
field of lipids prompted us to prepare deuterated leukotrienes as stable standard compounds. Thus, chiral [11,12,14,15]-tetradeuterated LTA4methylester 4b was synthesized by reduction of the appropriate diyne precursor and will lead to the corresponding tetradeuterated peptidoleukotrienes.

A simple one-steppreparation of the sulfones of Leukotriene C4, D4 and E4 has been developed by the direct oxidation of the parent compounds. An alternative synthesis of these sulfones has also been carried out by reduction of an acetylenic precursor.

Tritiated leukotriene A(4) and 8-epi-prostaglandin F-2 alpha methyl esters were prepared from the corresponding acetylenic precursors by selective reduction with tritium gas to provide a probe for the metabolite identification of these oxylipins. Partially deactivated Pd-catalysts were prepared from commercial products and their composition was optimized to achieve the better selectivity. A micro-method for the saponification of labelled oxylipins methyl esters was used.
