## Abstract __Erthro__‐1‐dehydrohexestrol (**4a**), an analog of the nonsteroidal estrogen __meso__‐hexestrol containing a double bond in the side chain, has been synthesized as a general precursor for the preparation of tritium‐labeled hexestrol derivatives. It can be functionalized further as nee

✦ Synopsis
In the interest of developing efficient methods for tritium labelling peptides, we here demonstrate the successful labelling of PACAP‐38 (pituitary adenylate cyclase‐activating polypeptide), a 38‐mer peptide, using a synthetic diiodinated PACAP‐38 precursor. In this example, we employ standard hydrogenation chemistry with the use of a heterogeneous palladium catalyst and carrier‐free tritium gas on a tritium manifold system.
