Abstract
[6β‐^2^H] Testosterone and [6β‐^3^H] Testosterone were each synthesized in good yield in three steps: Treatment of 5a, 6a‐ epoxy‐3, 3‐ethylene‐dioxyandrostan ‐17β‐ol with labelled lithium aluminum hydride is followed by deacetalation and dehydration under carefully controlled basic conditions.
