ABSTRACT
3alpha-Hydroxy-5alpha-pregnane-11,20-dione-[21-14C] and 3alpha,21-dihydroxy-5alpha-pregnane-11,20-dione-[21-14C] 21-acetate were prepared from a common radio-labelled intermediate, 21-diazo-3alpha-hydroxy-5alpha-pregnane-11,20-dione-[21-14C] 3-nitrate, obtained by the reaction of 17beta-chlorocarbonyl-3alpha-hydroxy-5alpha-androstan-11-one 3-nitrate with diazomethane-[14C].
