Abstract

We have synthesised prednisone and prednisolone labelled with four deuterium atoms at chemically stable sites ([1,19,19,19‐^2^H~4~]prednisone and [1,19,19,19‐^2^H~4~]prednisolone), starting from [1,1,19,19,19‐^2^H~5~]cortisone. The isotopic purities were demonstrated to be > 98 atom%. There were no indications of deuterium loss from the C‐19 and C‐1 positions during the synthetic sequence involving an oxidation reaction step using selenium dioxide in tert‐butanol.
