✦ Synopsis


The epimeric gibberellin-A 7-aldehydes 1 and 2 were silylated, enolised with KH and 3labelled with -3 H20 to give after desilylation the tritium-labelled epimeric gibberellin-A ?-aldehydes 2 and 2. Subsequent acetylation, oxidation and deacetylation afforded [ 6-3H] gibberellin-A3 (6) and [ 6-3H]6-epi-gibbercllin-A provides a convenient method for the preparation of [ 6-3H] GA3 of high specific radioactivity.

## Abstract Regiospecific syntheses of tritium labelled precocene I (**5a**) and precocene II (**5b**), the antijuvenile hormones, have been accomplished. The syntheses involved condensations between 2‐hydroxyacetophenones (**1**) with acetone‐T to give cross condensation products **2** which on cy
