<19-2H3>Progesterone has been prepared from 3,3:20,20-bisethylenedioxy<19-2H3>pregn-5-en-19-ol by reduction of the derived 19-toluene-p-sulphonate with lithium triethylborodeuteride ('superdeuteride') followed by hydrolysis of the ethylenedioxy groups. <18-2H3>Progesterone was obtained from (20R)-3β-acetoxy-pregn-5-eno-20,18-lactone via conversion into methyl (20R)-3β-20-dihydroxypregn-5-en-18-oate: a two-stage introduction of three atoms of deuterium at C-18 via the toluene-p-sulphonate of the derived <18-2H2>-18-ol required unusual experimental conditions.
