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