Abstract The synthesis of two forms of selectively deuterated 17-methyl-testosterone is described. 17-Methy1-d 3-testosterone was prepared by the Grignard reaction of dehydroepiandrosterone with deuterium labeled methyl magnesium iodide followed by an Oppenauer oxidation. 17-Methyl-d 3-testosterone-19, 19, 19-d 3 was prepared by treating 3, 3-ethylenedioxy-5, 10-epoxy-5α, 10α-estran-17-one with deuterium labeled methyl ...
