## Abstract Mazindol was labeled with tritium in the 6,9 positions in low yield starting with dimethyl phthalate‐3,6‐^3^H which was prepared by reduction of dimethyl 3‐chlorophthalate with tritium gas using 10% palladium on charcoal as a catalyst. The labeled dimethyl phathalate was hydrolisized wi

## 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
