## Abstract Deuterium and tritium 5,7,7‐tris‐labelled 24‐epibrassinolide were prepared by base catalyzed exchange reaction using 24‐epicastasterone tetraacetate 1 or bis‐isopropylidenedioxy‐24‐epicastasterone 8 and labelled water. Baeyer‐Villiger oxidation of the obtained labelled 6‐ketones 2 and 3
