The microbiological transformation of 17β-hydroxy-A-nor-5α-androstan-2-one, 17β-hydroxy-A-homo-5α-androstan-3-one and 5α-androstan-3,17-dione, by Cunninghamella elegans is dominated by 9α-hydroxylation whereas 17β-hydroxy-5α-androstan-3-one undergoes predominant 7α-monohydroxylation. 9α-Hydroxy-5α-androstane-3,17-dione and 9α-hydroxy-A-homo-5α-androstane-3,17-dione were synthesised by a sequence involving 11α-hydroxylation of the corresponding 3,17-diones by Aspergillus ochraceous.
