## Abstract A new hepatoprotective agent, N‐(2‐hydroxyethyl)‐maleopimarimidyl morpholide (RU18492) has been synthesised labelled with tritium at C‐3, C‐4a, C‐10 and in the C‐isopropyl group. The incorporation of tritium relies on the acid‐catalysed isomerisation of levopimaric acid (4) to abietic a

## Abstract Phenylacetia acid has been labeled by means of the nuclear reaction ^6^Li(n,α)^3^H, both in mixture with Li~2~CO^3^ and as the lithium salt. The amount of Li~2~ CO^3^ was such as to keep the same weight ratio of lithium and phenylacetate ion as in the salt. It was observed that intimat
High specific activity methyl-butyrate-2,3-H3 and methyl-stearate-9,lO-H3 were stored for approximately three months. The self-radiolysis decomposition products were identified by means of radio-gas chromatographic methods and the isotopic dilution technique. Rather high G-values were found for the
## Abstract A method for tritium labelling of jasmonic acid, ethyl dihydrojasmonate, and itaconic acid involving metal catalyzed hydrogen isotope exchange is described. The procedure is a convenient one‐step synthesis and specific activities in the range of 3 to 30 GBq/mmol were obtained.
On hydrogenation of the 2,6-bis(phenylhydrazone) of 2,6-diketopimelic acid with carrierfree tritium a very low specijic activity was achieved, due to the labile C-T-bonds in the a-positions. 2,6-Di~minopimelic-4-~H acid of spec. activity 790 mCilmmole was obtained by catalytic dehydrohalogenation of
