β , 16 β -diol. The fungus Cephalosporium aphidicola has been shown to hydroxylate 5 α -androstane-3, 16-dione predominantly at the C-6 β position with minor hydroxylation occurring at the C-7 α and C-14 α positions. In contrast hydroxylation of the 3 β , 16 β -diol took place at C-11 α . The 3 β -hydroxy-16 α , 17 α -epoxide was hydroxylated at the C-6 β position.
